Answer: Option (b) is the correct answer.
Step-by-step explanation:
During the day, ocean water absorbs heat from the sun. As a result, this heat evaporates the water and rises into the atmosphere.
This heated air expands and reaches to the land or region which are colder as compared to it.
Therefore, we can conclude that air that comes in from the ocean during the day is usually warmer than the air on land.
