D
Wind coming in from the sea
Explanation: 

Detailed explanation-1: -sea breeze, a local wind system characterized by a flow from sea to land during the day. Sea breezes alternate with land breezes along the coastal regions of oceans or large lakes in the absence of a strong large-scale wind system during periods of strong daytime heating or nighttime cooling.

Detailed explanation-2: -The winds that blow from the sea towards the land are called sea breezes. During day time land heats up fast and the air above land rises. This creates a low pressure region over the land and a high pressure in the sea, this causes the winds to start blowing.

Detailed explanation-3: -Land Breeze: In the night the reversal of condition takes place. The land loses heat faster and is cooler than the sea. The pressure gradient is from the land to the sea and hence land breeze results.

Detailed explanation-4: -Recall that the land surface cools quicker than the water surface at night. Therefore, the warmer air over the ocean is buoyant and is rising. The denser cool air over the land is flowing offshore to replenish the buoyant warm air and is called a land breeze.
