The correct answer is C. Direct sunlight and rainy days.
Explanation
The equator is a latitudinal area of the Earth located between 0 ° and 23 ° latitude (towards the north and south). This area has particular climatic characteristics defined by the direct incidence of the sun's rays. This characteristic means that this place lacks seasons (spring, summer, autumn, and winter) and, on the contrary, has a climatic pattern of drought and seasonal seasons. Rainfall is determined by the movement of the Intertropical Convergence Zone in which the north and south winds meet, forming a latitudinal strip of clouds that cause abundant rainfall during the rainy season. So the correct answer is C. Direct sunlight and rainy days.
