Why is actual distance different even though India's latitudinal and longitudinal extents are nearly similar in degrees?

Correct answer: The distance between longitudes changes with latitude

The governing concept is the unequal ground distance represented by degrees of longitude and latitude. Lines of latitude are parallel, so one degree of latitude represents nearly the same north–south distance everywhere. Meridians of longitude, however, converge toward the poles; consequently, the east–west distance represented by one degree of longitude becomes smaller as latitude increases. India’s angular latitudinal and longitudinal spans may look similar on a map, but their kilometre equivalents need not be equal. Option A is correct. Option B is false because latitude lines are separated, while C and D confuse coordinate lines with area and coastline.
