A Ground Fault Circuit Interrupter (GFCI) is primarily designed to protect against electric shock. It functions by monitoring the current flowing through a circuit. If it detects an imbalance—indicating that some of the current is flowing through an unintended path, such as water or a person— it quickly disconnects the power, significantly reducing the risk of serious injury or death from electric shock.

The option about fire relates to different mechanisms, such as circuit breakers or fuses that protect against overheating or overcurrent, which can lead to fire hazards but do not specifically address shock protection. Overheating and overcurrent protect against conditions that can damage equipment or wiring but do not directly prevent electrical shocks, which is the main purpose of a GFCI.
