Why is latitudinal extent considered a broader fact than only north-south distance in studying India's size and extent?

Correct answer: It is also linked with climate, temperature and regional diversity

Option A is correct because latitudinal extent describes more than a north–south measurement. Latitude determines the angle and intensity of incoming solar radiation, so a country extending across several degrees of latitude can experience changes in temperature, duration of daylight, seasons, and broad climatic conditions. In India, the north–south spread helps explain regional differences between the tropical south and the subtropical Himalayan and northern areas, although relief, altitude, distance from the sea, and monsoon circulation also modify climate. Coastline length is not measured by latitude alone, longitudes are not reduced by latitudinal extent, and world area rank depends on total area, not directly on latitude. Thus A gives the broad geographical significance.
