Which one of the following pairs of States of India indicates the easternmost and westernmost State?

1. A

   Assam and Rajasthan

   (a) Assam and Rajasthan. Assam is not India’s easternmost State (Arunachal lies further east). Rajasthan is not the westernmost (Gujarat’s Kachchh extends further west). Both ends are wrong.

2. B

   Arunachal Pradesh and Rajasthan

   (b) Arunachal Pradesh and Rajasthan. Arunachal is the easternmost State, but Rajasthan is not westernmost; Gujarat reaches a more westerly longitude. The pair fails on the west.

   Assam and Gujarat

   (c) Assam and Gujarat. Gujarat is westernmost, but Assam is not easternmost. The east end is wrong.

4. D
