As feet are to shoes, so head is to

The correct answer is (c) hat.

Feet are the parts of the body that we use to walk. Shoes are worn on the feet to protect them from the elements and to provide comfort. In the same way, a hat is worn on the head to protect it from the sun, rain, and cold.

(a) Umbrella is not the correct answer because it is used to protect the body from the rain and sun, not the head.

(b) Comb is not the correct answer because it is used to style the hair, not to protect the head.

(d) Hair is not the correct answer because it is a part of the body, not an object that is worn on the head.
