What do the arrows indicate? Air moves in a direction that creates land breezes.
Air above land warms faster than air above water.
Air blows over long distances in a continual straight path.
Air pressure remains the same while cycling over land and water.

The best answer would be:

The first option.

Air moves in a direction that creates land breezes.

If you'd like to know more about this, you can read on:

The arrows show how air moves as land breezes are created. In coastal areas, land cools much faster than water, so what happens is the air above it gets cooled down. When this happens, it becomes more dense moves downwards towards land. This causes high pressure and cause winds to blow outwards towards water (ocean).
