$(b)$. Instead of metal wires, a jute string can be used to make a circuit.
$(c)$. Electric current can pass through a sheet of thermo Col.

$(a)$. Electric current can flow through metals.

True, as metals are good conductor.

$(b)$. Instead of metal wires, a jute string can be used to make a circuit.

False, as jute is an insulator.

$(c)$. Electric current can pass through a sheet of Thermocol.
