The easternmost state of India (mainland) is Arunachal Pradesh, and the westernmost state (mainland) is Gujarat.
Arunachal Pradesh is located in the northeastern part of India and is the state that receives the first sunrise in the country due to its longitudinal extent. Its easternmost point is near Kibithu.
Gujarat is located on the western coast of India. Its westernmost point on the mainland is in the Kutch region, near Ghuar Mota.
Comparing the options, Arunachal Pradesh and Gujarat represent the easternmost and westernmost states, respectively.
Assam is to the west of Arunachal Pradesh. Rajasthan is to the northeast of Gujarat but not the westernmost state.
The difference in longitude between Arunachal Pradesh (approx. 97.25° E) and Gujarat (approx. 68.1° E) leads to a time difference of about two hours between the eastern and western parts of India.
