Answer:

Hey friend

The answer will be (4) Either LED or a coil wounded over a compass needle.

It is BECAUSE LED means Light Emitting Diode glow even when a small amount of current passes through it. And second is a coil wounded over a compass needle. If a small amount of current passes through it then the needle will show some deflection.

HOPE IT HELPS YOU...
