Correct Answer: Arid

Solution : The second option is the correct choice.

Damp refers to a slight wetness or moisture, often describing something that is not completely wet but has a degree of humidity or moisture.

Arid , on the other hand, means extremely dry or lacking moisture. It is the opposite of dampness, indicating a state of dryness or aridity.

The meanings of the other options are:

Misty: It is characterised by or full of mist; obscured by or covered with mist.

Tropical: It means relating to or characteristic of the tropics; a hot and humid climate typical of regions near the equator.

Soaked: It means completely wet or saturated with liquid, typically water.

Therefore, "Arid" is the antonym that best contrasts with "Damp" among the options provided.
