Concept:The Torrid Zone gets maximum heat because the sun's rays fall vertically, concentrating energy over a small area.
Explanation:The Torrid Zone lies between the Tropic of Cancer and the Tropic of Capricorn.
Here, the mid-day sun is exactly overhead at least once a year.
Vertical rays travel a shorter path through the atmosphere, losing less heat.
This direct angle delivers more solar energy per unit area than slanting rays.
Other options (slanting rays, landlocked, ocean-bounded) do not cause maximum heating.
Answer:D. the mid-day sun is exactly overhead
