option a is correct.
Temperature is controlled by cold air advection and convection.
By advection. cold air moves horizontally to warm region controlling its temperature.
Convection is a vertical phenomenon that occurs in a beaker of boiling water, the atmospheres of the Earth and some other Solar System objects, the interior of the Earth and many other Solar System objects, the interior of the Sun and other stars.
