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

Arunachal Pradesh is the easternmost state containing the point Kibithu (97°25' E), while Gujarat is the westernmost state containing Guhar Moti (68°7' E). Options involving Assam or Rajasthan are incorrect because, despite their proximity to the borders, they do not reach the longitudinal extremes of the Indian mainland. The core concept tested is the geographical location of India's extreme cardinal points and its overall longitudinal extent.
