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

Whether the engine is in an off condition. The alternator will supply the power to battery? Tell me anyone.

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

Alternators are used in modern automobiles to charge the battery and to power the electrical system when its engine is running.

Until the 1960s, automobiles used DC dynamo generators with commutators.

Alternator is also in the genrator its main work is convert mech energy into electrical energy.

The alternator is only converting to mechanical energy convert to electrical energy. Alternator not a full-time charge. Because alternator together fit for the regulator.

B is correct because first, it converts mechanical energy to electrical energy then it convert ac to dc then it supplies to the battery for storage and uses in Application.

Option C is right but option B is also right because main function of alternator is to convert mechanical energy into electrical energy.

The answer should be D as the energy input to alternator is mechanical energy as it is rotating on the revolution of shaft and this revolutions (mechanical motion) is transferred to the alternator for the generation of electricity. The supply is takes place by Battery. Answer is right that continuously charging the battery but the basic work of alternator is to change mechanical energy to Electrical.

Basically, it's just a converter which use engine power and convert that into electrical energy and that in turn leads to the charging of the battery! The principle of the alternator is the rotating magnetic field that generates electricity.
