Answer: b) circuit breaker interrupt
Explanation:
Wires connect to outlets through terminals and these terminals need to be tight to ensure that electricity flows with the minimum amount of resistance.
If the terminal is poorly tightened, what happens is that resistance will build up as the appliance is being used and this resistance will make the terminal hotter.
The heat will continue to rise until the circuit breaker trips to interrupt the circuit and protect the appliance.
