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.
