When you touch a charged body, the charge flows through you into the earth. This is called
(A) induction
(B) conduction
(C ) capacitance
(D ) earthing

Hint: When an object with some charge appears to be in contact with the earth the charge may flow into the earth and as a result they get discharged. This process is the process of earthing. The potential across it comes to zero physically in earthing. But the potential becomes zero but not physically connected to ground.

Complete step by step answer:
When an object with some charge appears to be in contact with the earth the charge may flow into the earth and as a result they get discharged. This process is the process of earthing. It also acts as a protective device in household circuits. While earthing the potential across it comes to zero physically. Whereas, grounding is also similar to this. That is, the potential becomes zero but not physically connected to ground.
The induction can be described as a generation of induced emf when there is a changing magnetic field across it. The capacitance can be said to be the ratio of charge to the potential. And conduction is the process by which heat energy is transmitted from one to another.

Therefore option (D) is correct.
