Consider the following pairs : Glacier River 1. Bandarpunch : Yamuna 2. Bara Shigri : Chenab 3. Milam : Mandakini 4. Siachen : Nubra 5. Zemu : Manas Which of the pairs given above are correctly matched?

Result
Your answer: —  ·  Correct: A
Explanation

The correct answer is option A (pairs 1, 2, and 4 are correctly matched).

**Pair 1 (Bandarpunch-Yamuna)** is correct: The Yamuna originates from the Yamunotri Glacier on the western slopes of Banderpunch range (6,316 m)[2], establishing a direct connection between Bandarpunch and the Yamuna River.

**Pair 2 (Bara Shigri-Chenab)** is correct: Bara Shigri glacier is located in Chandra Valley of Lahaul in Himachal Pradesh and is a source of water for River Chenab[3]. Additionally, the Chenab is known as Chandra-Bhaga in Himachal Pradesh, and the Chandra and Bhaga tributaries originate on either side of the Bara-Lacha Pass in Lahul District[4].

**Pair 4 (Siachen-Nubra)** is correct: Nubra river emerges from the Karakoram glaciers[5], and the Shyok-Nubra tributaries arise from the Siachen Glacier (Karakoram Range)[6].

**Pair 3 (Milam-Mandakini)** is incorrect because Milam glacier is the major source of River Gori Ganga[3], not Mandakini. **Pair 5 (Zemu-Manas)** is incorrect as Zemu glacier feeds River Teesta[7], not Manas.

This is a textbook 'Table-Lift' question. The pairs are directly sourced from the 'List of Glaciers' tables found in standard books like Majid Husain (Table 2.3) and NCERT. It rewards rote memorization of specific Glacier-River linkages rather than conceptual understanding.

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

Statement 1
In the Indian Himalaya, is the Bandarpunch glacier a source or main feeder of the Yamuna River?
Origin: Direct from books Fairness: Straightforward Book-answerable
From standard books

Presence: 5/5
“This is the longest (1380 km) and the western-most tributary of the Ganga. Its source lies in the Yamunotri Glacier on the western slopes of Banderpunch (6316 m). Downwards, it is joined by Tons river behind the Mussoorie Range (Uttarakhand). From the Mussoorie Range, it debouches into the plains where it flows in a broad curve. Making a boundary between Haryana and Uttar Pradesh, it passes Delhi, Mathura, Agra and flows southward until it joins the Ganga at Allahabad. The important tributaries of the Yamuna are mostly the right bank tributaries, originating from the Aravallis (Rajasthan), Vindhyan Range, and the Malwa Plateau of Madhya Pradesh.”
Why this source?
  • Identifies the Yamuna's source as the Yamunotri Glacier located on the western slopes of Banderpunch (6316 m).
  • Directly links the Banderpunch massif area with the origin of the Yamuna River.

“river system is the largest in India having a number of perennial and non-perennial rivers originating in the Himalayas in the north and the Peninsula in the south, respectively. The Son is its major right bank tributary. The important left bank tributaries are the Ramganga, the Gomati, the Ghaghara, the Gandak, the Kosi and the Mahananda. The river finally discharges itself into the Bay of Bengal near the Sagar Island. The Yamuna, the western most and the longest tributary of the Ganga, has its source in the Yamunotri glacier on the western slopes of Banderpunch range (6,316 m). It joins the Ganga at Prayag (Allahabad).”
Why this source?
  • States the Yamuna is the westernmost longest tributary of the Ganga and has its source in the Yamunotri Glacier on the western slopes of Banderpunch range (6,316 m).
  • Reinforces the Bandarpunch–Yamunotri connection and the river's Himalayan glacial origin.

“The Ganga is joined by many tributaries from the Himalayas, a few of them being major rivers, such as the Yamuna, the Ghaghara, the Gandak and the Kosi. The river Yamuna rises from the Yamunotri Glacier in the Himalayas. It flows parallel to the Ganga and as a right bank tributary meets the Ganga at Allahabad. The Ghaghara, the Gandak and the Kosi rise in the Nepal Himalaya. They are the rivers, which flood parts of the northern plains every year, causing widespread damage to life and property, whereas, they enrich the soil for agricultural use. The main tributaries, which come from the peninsular uplands, are the Chambal, the Betwa and the Son.”
Why this source?
  • Confirms the Yamuna rises from the Yamunotri Glacier in the Himalayas.
  • Provides independent support that the Yamuna's primary source is a Himalayan glacier (Yamunotri).
