But the first alternator converts mechanical to electrical energy then it recharges the battery.

So, I think option B is the correct answer.

Generally, alternator converts mechanical energy into electrical energy but in question, they asking the use of alternator in an automobile so generally automobile it recharge the battery and along with this it provides electrical energy to the automobile electrical system when engine is running condition. So during vehicle running condition battery does not provide electric power to automobile.
