Option (B)
Explanation:
The temperature difference occurs due to the unequal heating of the earth's surface, and this results in the creation of wind that blows from a region of higher pressure to low pressure in order to stabilize it.
There occurs maximum temperature difference between the surface air and the air above it. It is because during a calm and sunny day, the earth's surface gets heated up more readily in the morning time, increasing its absorption of incoming solar radiations and this heat is stored till the evening, but the air above this surface air are relatively colder because they are replaced by the comparatively colder air. So, during the afternoon in this type of day, there occurs the highest temperature difference.
Thus, the correct answer is option (B).
