Wind blows from a lake toward the land during daytime hours, as shown in the diagram below.

Based on the information in the diagram, how does the Sun cause wind to blow from the lake toward the land during the day?
A.
The Sun spends different amounts of time heating the land and the lake, keeping air pressures different.
B.
The Sun spends equal amounts of time heating the land and the lake, keeping air pressures the same.
C.
Uneven heating by the Sun creates pressure differences between the air over the land and the air over the lake.
D.
Equal heating by the Sun keeps pressures the same between the air over the land and the air over the lake.
