### The power source for Battery Electric Vehicles

• A.

Rechargeable batteries

• B.

Gasoline

• C.

Regenerative Braking System

• D.

None of the Above

A. Rechargeable batteries
Explanation
Battery Electric Vehicles (BEVs) are powered by rechargeable batteries. These batteries store electrical energy and provide it to the electric motor, which propels the vehicle. Unlike hybrid vehicles, BEVs do not have an internal combustion engine and therefore do not require gasoline as a power source. Instead, they rely solely on the energy stored in their rechargeable batteries. Another option, regenerative braking system, is a technology that allows the vehicle to recover and store some of the energy that is normally lost during braking. However, this system alone cannot be considered as the primary power source for BEVs.
