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

1. The question asks to identify the pair of States of India that represent the easternmost and westernmost extent of the country. 2. The easternmost point of mainland India is near Kibithu in the Anjaw district of Arunachal Pradesh. Therefore, Arunachal Pradesh is the easternmost State. 3. The westernmost point of mainland India is Guhar Moti, near Sir Creek in the Kutch district of Gujarat. Therefore, Gujarat is the westernmost State. 4. Thus, the correct pair indicating the easternmost and westernmost State is Arunachal Pradesh and Gujarat. 5. Option (A), (B), and (C) are incorrect because they either do not include the easternmost state (Assam instead of Arunachal Pradesh) or the westernmost state (Rajasthan instead of Gujarat).
