Why can India's north-south extent be considered not only a distance but also a climatic indicator?

Correct answer: Because it passes through different latitudes

Option A is correct because India’s north-south span crosses a substantial range of latitudes. Latitude affects the angle at which solar energy reaches the surface, the length of seasons, and general temperature patterns. Consequently, the southern peninsula is generally more tropical, while northern areas experience greater seasonal contrasts and, in some regions, colder winters. Relief, altitude, distance from the sea, and monsoon circulation also modify climate, so latitude is an important indicator rather than the only cause. Longitudes do not disappear, the span is not merely a maritime boundary, and area cannot be converted into a climate explanation by itself.
