Question

car makers have an idea about changing the body of a car so that the car would not need a battery. the body of the car would be able to a store energy. b become larger or smaller. c change color. d fix itself after a crash.

Explanation:

The problem is about a car design where the body replaces the battery's function. Batteries store energy, so the car body would need to store energy. Option B (changing size) is unrelated to energy storage, C (changing color) is cosmetic, and D (self - repair) doesn't relate to energy storage like a battery. So the correct option is A.

Answer:

A. store energy.
