What happens in a global convention cell?

The correct answer is option c, Cool  Air moves upward in the center Warm  air moves downward at the edge

Reason:  

In a global convection cell less –dense air at the equator rises and flows towards the poles. And from pole, the dense air sinks down and flows back towards the equator. The equator is the center of the earth’s sphere while the poles can be considered to be the longitudinal edges. This movement of air is also supported by the Earth’s rotation known as Coriolis Effect.  

warm air moves upward in the center, cool air moves downward at the edge
