Which of the following is geographically closest to Great Nicobar ?

Result
Your answer:  ·  Correct: A
Explanation

The Andaman and Nicobar Islands are strategically located, bifurcating the Bay of Bengal from the Andaman Sea, and are in proximity to the Strait of Malacca.[3] Great Nicobar is the southernmost island of the Andaman and Nicobar archipelago. Geographically, Sumatra (Indonesia) lies directly across the narrow channel south of Great Nicobar, separated by a distance of approximately 150 kilometers at the closest point. This makes Sumatra significantly closer than the other options. Sri Lanka is located far to the west in the Bay of Bengal, while Borneo lies to the southeast and Java is positioned much further south in the Indonesian archipelago. The proximity of Great Nicobar to Sumatra is strategically significant, as both flank the vital Strait of Malacca shipping route.

This is a classic 'Atlas-Derived' question. Standard books (NCERT/Majid Husain) mention Indira Point and the strategic location near Malacca, but no text explicitly compares distances to these four options. It penalizes 'text-only' readers and rewards those who actively visualize the 'Mental Map' of the Indian Ocean Region.

How this question is built

This question can be broken into the following sub-statements. Tap a statement sentence to jump into its detailed analysis.

Statement 1
What is the shortest distance between Great Nicobar (Andaman and Nicobar Islands, India) and the island of Sumatra (Indonesia)?

Strength: 5/5
“The main islands of the Bay of Bengal are the Andaman and Nicobar groups. The Andaman and Nicobar islands are separated by the Ten Degree Channel. The shortest distance of the Andaman Islands from the mainland (Bay of Bengal Head) is about 2000 km and the extreme southern point is the Indira Point—the southern most point of the Great Nicobar Island (Fig. 2.23).”
Why relevant

Identifies Indira Point as the extreme southern point of Great Nicobar, providing a concrete reference location on Great Nicobar that should be used when measuring to Sumatra.

How to extend

A student can take Indira Point as the precise endpoint on Great Nicobar and then use a map or coordinates to measure the nearest distance to Sumatra.

“India is a vast country. Lying entirely in the Northern hemisphere (Figure 1.1) the main land extends between latitudes 8°4'N and 37°6'N and longitudes 68°7'E and 97°25'E. The Tropic of Cancer (23° 30'N) divides the country into almost two equal parts. To the southeast and southwest of the mainland, lie the Andaman and Nicobar islands and the Lakshadweep islands in Bay of Bengal and Arabian Sea respectively. Find out the extent of these groups of islands from your atlas. • The southernmost point of the Indian Union– 'Indira Point' got submerged under the sea water in 2004 during the Tsunami.”
Why relevant

Gives India's southern latitude extent (about 8°4'N), indicating Great Nicobar lies very near the southern limit of India and hence relatively close to equatorial/SE Asian islands like Sumatra.

How to extend

Use the latitude hint plus a world map or atlas to locate Great Nicobar relative to Sumatra and estimate/compute the shortest separation (e.g., via latitude/longitude differences or map scale).

“There are 556 islands in the Union Territory of Andaman and Nicobar Islands. Out of these 36 are permanently inhabited. Most islands are in the Andaman group, 26 of which are inhabited. The Nicobar islands comprises 22 main islands (10 inhabited). The Andaman and Nicobar Islands are separated by the Ten Degree Channel, about 150 km wide. The total area of Andaman Islands is about 6408 sq km, and that of Nicobar Islands approximately 1841 sq km. The Andaman and Nicobar Islands are endowed with tropical rainforest. These forests consists of a mixed flora with elements from Indian, Malaysian, and Myanmarese floral strains.”
Why relevant

States the Ten Degree Channel separates Andaman and Nicobar groups and gives a channel width (~150 km), illustrating that channel distances between nearby island groups are measured and reported in these sources.

How to extend

By analogy, a student can look for similar reported channel or sea-gap measurements (or measure on a map) between Great Nicobar (Indira Point) and Sumatra to obtain the shortest distance.

Pattern takeaway: UPSC has shifted from asking 'What is the southernmost point?' (Static Fact) to 'What is next to the southernmost point?' (Relative Geography). They test your spatial awareness of India's periphery, not just the mainland.
How you should have studied
  1. [THE VERDICT]: Visual Sitter. Not found in text, but obvious in any Oxford/Blackswan Atlas. If you only memorized 'Indira Point', you failed. If you looked at *where* Indira Point is, you scored.
  2. [THE CONCEPTUAL TRIGGER]: India's Maritime Neighbourhood & Strategic Chokepoints. Specifically, the 'Island Chain' theory connecting the Bay of Bengal to the Strait of Malacca.
  3. [THE HORIZONTAL EXPANSION]: Memorize the 'Channel Hierarchy': Coco Channel (Andaman-Myanmar), Duncan Passage (South-Little Andaman), 10 Degree Channel (Andaman-Nicobar), and the **Great Channel (Six Degree Channel)** which separates Great Nicobar from Sumatra (~150 km).
  4. [THE STRATEGIC METACOGNITION]: When a book says 'Strategic Location' or 'Near Malacca Strait', stop reading. Open the Atlas. Measure the gap with your finger. Realize that Great Nicobar is closer to Indonesia (Sumatra) than it is to Chennai or Sri Lanka.

🌑 The Hidden Trap

The 'Great Channel' (or Six Degree Channel). This is the specific maritime boundary between Indira Point (Great Nicobar) and Banda Aceh (Sumatra). It is a major international shipping lane. Expect a future question on the 'Six Degree Channel' specifically.

⚡ Elimination Cheat Code

Use the 'Malacca Strait' logic. You know Nicobar is strategic because it guards the entry to the Strait of Malacca. The Strait of Malacca is formed by Malaysia and **Sumatra**. Therefore, to guard it, Nicobar must be physically adjacent to Sumatra. Sri Lanka is on the other side of the Bay; Borneo and Java are too deep inside the archipelago.

🔗 Mains Connection

Mains GS3 (Security) & GS2 (IR): The 'Great Nicobar Transshipment Port' project is controversial precisely because of this geography. It aims to capture transshipment traffic from the Strait of Malacca (Sumatra side). This geography dictates India's 'Act East' maritime strategy.
