In coastal areas during nights, which of the following can be observed?

Land breeze

The correct answer is option 2. Land breeze.

During nights in coastal areas, land breeze can be observed. Land breeze occurs when the land cools more rapidly than the sea. At night, the land loses heat quickly, causing the air over the land to become cooler than the air over the warmer sea. As a result, the cooler air from the land moves towards the warmer sea, creating the land breeze. This phenomenon is the opposite of the sea breeze, which occurs during the day when the land heats up more quickly than the sea.
