Result
Your answer: —  Âˇ  Correct: D
Explanation

The easternmost longitude of India is 97° 25′ E, located at the easternmost tip of Arunachal Pradesh[1], making it the easternmost state of India. The mainland of India extends from Kashmir in the north to Kanniyakumari in the south and Arunachal Pradesh in the east to Gujarat in the west[2]. India's mainland extends between longitudes 68° 7' to 97° 25' East[3], with Gujarat being located at the western extreme (68° 7' E) and Arunachal Pradesh at the eastern extreme (97° 25' E). Therefore, Arunachal Pradesh and Gujarat represent the easternmost and westernmost states of India respectively.

“Y ou have already seen the map of India in the previous classes. Now you closely examine the map of India (Figure 1.1). Mark the southernmost and northernmost latitudes and the easternmost and westernmost longitudes. The mainland of India, extends from Kashmir in the north to Kanniyakumari in the south and Arunachal Pradesh in the east to Gujarat in the west. India's territorial limit further extends towards the sea upto 12 nautical miles (about 21.9 km) from the coast. (See the box for conversion). Statute mile | = | 63,360 inches • Col1: Nautical mile; Col2: =; Col3: 72,960 inches 1 Statute mile | = | about 1.6 km (1.584 km) 1 Nautical mile | = | about 1.8 km (1.852 km) Our southern boundary extends upto 6°45' N latitude in the Bay of Bengal.”
Why this source?
  • Explicitly states the mainland of India 'extends ... Arunachal Pradesh in the east to Gujarat in the west', naming both states as the east and west extremes of the mainland.
  • Directly identifies the two states (Arunachal Pradesh and Gujarat) as geographic end-points, allowing a student to name easternmost and westernmost states for the mainland.

“So (d) 92°30' E is the answer.• 97° 25′ E is the easternmost longitude of India (at the easternmost tip of Arunachal Pradesh). Thus, India experiences the first light of the sunrise along this meridian.”
Why this source?
  • Gives the easternmost meridian of India (97°25′ E) and ties that meridian to the easternmost tip of Arunachal Pradesh.
  • Reinforces Arunachal Pradesh as the eastern extreme by linking a precise longitude to that state.

“India lies entirely in the Northern Hemisphere. The mainland extends between latitude 8° 4' and 37° 6' North, longitudes 68° 7' to 97° 25' East, and measures about 3214 km from north to south and about 2933 km from east to west. It has a land frontier of about 15,200 km. the total length of the coastline of the mainland, Lakshadweep Islands, and Andaman and Nicobar Islands is about 7517 km. Countries having common border with India are Afghanistan and Pakistan in the north-west, China, Bhutan, and Nepal in the north, Myanmar in the east and Bangladesh to the east of West Bengal.”
Why this source?
  • States the longitudinal extent of the Indian mainland as 68°7' E to 97°25' E, corroborating the meridian cited for the eastern extreme.
  • Provides authoritative numeric bounds for mainland longitudes that support identifying extreme states by longitude.
