It's not true. The main function of the alternator and dynamo is converting the engine's mechanical energy to electrical energy.

It's not function, It is " purpose " actually.

But initially it converts mechanical energy to electrical energy, than it helps to recharge battery. So, initial step should be the actual answer.

An alternator supplies the power to run the vehicle electronics, ignition, lights etc and to charge the battery.

The battery has to deal with a huge power drain when starting. The alternative is a generator.

An alternator is a spinning magnet surrounded by a coil of wire, a generator is usually a magnetic field with a spinning coil of wire.

The above question answer is D because the alternator is not supplying continuous electrical power to the battery so its cut off the power supply partially by using the cut off the relay.

Alternator: An alternator is an electrical generator that converts mechanical energy to electrical energy in the form of alternating current. For reasons of cost and simplicity, most alternators use a rotating magnetic field with a stationary armature.

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.
