Answer:
As the sun warms the land, the air above the land warms too. The warmer, lighter air rises, and the cooler heavier air above the water moves in and replace the rising warm air
Step-by-step explanation:
In convection current, during a hot sunny day, the land is heated up and the air above the land becomes warm and rises upward because of their low density. The cool breeze from the sea with higher density moves downward to replace the risen warm air. This process is known sea breeze which happens in the day time.
Based on the given options, we can choose the first option.
