Final Answer :
B
Explanation :
To enable a non-cycling circuit breaker to close again after it has tripped, you should key off the ignition circuit to allow the breaker to cool down. This process resets the breaker, making it possible to close again safely. Other options like replacing it, shorting it with a jumper wire, or using aluminum foil are either unsafe or unnecessary for simply resetting a tripped breaker.
