What is charging by conduction?

Transferring charge by moving electrons
Charging an object using a conductor
Charging an object by contact with a charged object
Creating static electricity through motion

The correct answer is: Charging an object by contact with a charged object

Charging by conduction is the process of charging an object by contact with a charged object. This means that charge is transferred from one object to another through direct contact, rather than through the movement of electrons (option A), charging an object with a conductor (option B), or creating static electricity through motion (option D). Charging by conduction relies on the physical contact between the two objects, whereas the other options do not necessarily require contact for charge to be transferred.
