The correct answer is: C. A battery
A battery is a device that converts chemical energy into electrical energy. It does this by using a chemical reaction to create an electric current. The current can then be used to power devices, such as flashlights, cell phones, and cars.
An atomic bomb is a device that uses nuclear fission to release a large amount of energy. Nuclear fission is a process in which a heavy nucleus splits into two smaller nuclei. This process releases a large amount of energy, which can be used to create an explosion.
A dynamo is a device that converts mechanical energy into electrical energy. It does this by using a rotating coil of wire to generate an electric current. The current can then be used to power devices, such as generators and motors.
An electric heater is a device that uses electricity to heat a material. The heat can then be used to warm a room, cook food, or dry clothes.
In conclusion, the only option that converts chemical energy into electrical energy is a battery.
