WBCS Main Examination 2022 — Paper III: General Studies I · Question 185 of 200

Answer: (D) Kanyakumari

In January the sun is overhead in the southern hemisphere, near the Tropic of Capricorn, so the place nearest the equator gets the most direct rays and the longest day; Kanyakumari (about 8°N) is the southernmost of these places. Chennai (about 13°N) is the tempting option but lies further north. Delhi and Amritsar, far to the north, get slanting rays and short days in winter. Insolation is the incoming solar radiation received at the earth's surface.
