India's latitudinal extent shows which geographical spread?

Correct answer: North–south spread

The governing concept is the distinction between latitude and longitude. Parallels of latitude run from west to east, but they measure how far a place lies north or south of the Equator. Therefore, the difference between India's northern and southern latitudes represents its north–south extent. It does not describe ocean depth or population density, and east–west spread is primarily expressed through longitude. Thus, option B is correct. Remember that a larger latitudinal range may also produce differences in climate, temperature, and length of day, although the direct answer here concerns geographical direction rather than climate.
