Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Heater wire must have high resistance than connecting wires so that most of the potential drops across the heater wire. because in series the more the resistances, the more the potential difference.Obviously, it should have high melting point.
