Answer:
The temperature over the land has become higher than the temperature over the water.
Explanation:
The air over the warmer land becomes heated and rises, and the cooler and denser air over the water moves in to take its place.
A is wrong. Clouds move where the upper air currents take them.
B is wrong. The highest air temperature of the day may still be lower than that of the air over the water.
D is wrong. Higher air temperature over the water would create a land breeze.
