Answer: Option (d) is the correct answer.
Step-by-step explanation:
When cool, dense air from over the water flows inland, it's called a sea breeze.
Any wind that travels from large body of water towards the inland is known as sea breeze. Land absorbs heat from the sun more readily as compared to water in the sea.
Therefore, the wind above the land is warm whereas the wind above the sea is cooler and dense.
