Hint:In this question, we use the primary idea of charging that the entity that is to be charged should be at a lower potential in comparison to the source because the flow of electrons will form a higher potential towards a lower potential. The energy that flows between the supply and the body to be charged is saved inside in the form of chemical energy. This will help to get the proper answer.
Complete answer:

As we recognize that the flow of electrons is constantly from higher voltage supply to lower voltage supply. In the case of battery charging of a motor vehicle, the source voltage needs to be more than the battery voltage. In any other case reversal of flow of electrons happens.
In this situation, the battery behaves as a sink so the direction of the current is reversed. So, the source voltage is constantly more than the battery voltage to charge the battery. The energy that's made from voltage, current, and time is saved withinside the battery in the form of chemical energy.
That is, it is primarily based totally at the conversion of electrical energy into chemical energy. According to the conservation of energy, energy can neither be created nor be destroyed; it is simplest transformed from one form into some other form.
The rate of charging the battery is depending on the voltage difference between the source voltage and the battery voltage, the better the difference, the better the rate of charging.
Hence in charging the battery of a motor automobile chemical effect of electrical current is used.
Hence, the correct option is C.
Note:Heating is there every time there is a flow of electrons however it only results in the lack of energy and has no significance in charging. When the electrons moving among different potentials collide with each other there is a lack of kinetic electricity and this accounts to the manufacturing of heat in the system.
