The correct option is option (c).

The bulb in the circuit C will glow up.

Complete circuit:

We know that for the light bulb to glow up, there must be finite current flowing in the circuit through the bulb.

But, for the current to flow in the circuit, first, the circuit must be complete.

As we can see in the figure provided in the question, circuit A is not complete, whereas circuit B, C, and D are complete. So from here we can reject the circuit A.

Now, the circuit B contains wood, circuit C contains silver and circuit D contains yarn. Only silver is an electrical conductor.

Therefore, circuit C is complete and current will flow through the bulb and it will glow up.
