Concept:A tropical continent is one whose larger part lies between the Tropic of Cancer and the Tropic of Capricorn.
Explanation:Africa is described as the most tropical continent because most of its landmass is located within the tropics.
The Tropic of Cancer is at
23.5∘N, while the Tropic of Capricorn is at
23.5∘S.
A major part of Africa extends between these two latitude lines.
As a result, most areas of Africa receive intense sunlight and experience tropical climates and vegetation.
Being astride the Greenwich Meridian or having free movement of people does not make a continent tropical.
Also, Africa is not near the poles, so option D is incorrect.
Therefore, the correct reason is simply that most parts of Africa lie within the tropics.
Answer:A. Most parts of Africa lies within the tropics
