Answer 1

Hint: Longitudinal differences can lead to this state. Arunachal Pradesh lies on the eastern side of the nation. The sun rises from the east side and moves toward the western side.

Complete Answer:
Sun rises earlier than Gujarat in Arunachal Pradesh. Arunachal Pradesh lies on the easternmost tip of the world, and Gujarat lies on the westernmost tip, and the two states are separated by a long distance. The spatial difference between the two points is 30 degrees and the time taken by the sun to cross each length is 4 minutes. Therefore it takes 2 hours before the sun hits Gujarat.

The latitudinal extent affects the length of the day and night as one travels from the south to the north. Arunachal Pradesh sits on the easternmost longitude, so the sun rises first in the state.

Therefore, Choice B is the correct answer.

Note: The shortest distance from Gujarat to Arunachal Pradesh is around 2457 kilometres. The time along the Standard meridian of India passing through Mirzapur which is in Uttar Pradesh is taken as the standard time for the whole country which is the reason as to why in spite of the difference, same time is shown on watches.
