Detailed Solution

Assertion (A): The latitudinal extent influences the duration of day and night, as one moves from south to north of India.
Reason (R): From Gujarat to Arunachal Pradesh there is a time lag of two hours.

Explanation:

The Assertion (A) is true because the latitudinal position (distance north or south of the equator) affects the length of day and night. Near the equator (like southern India), day and night are almost equal (about 12 hours each) throughout the year. As one moves northwards (towards northern India), the duration of day and night varies significantly with seasons due to the tilt of the Earth’s axis.
The Reason (R) is not correct in this context. The time lag of two hours from Gujarat to Arunachal Pradesh is due to the difference in longitude, not latitude. Longitude differences cause different local solar times.
