What is a common use for GFCI outlets?

GFCI outlets, or Ground Fault Circuit Interrupters, are specifically designed to protect against electrical shock in areas where water is present. This includes locations such as kitchens and bathrooms, where the likelihood of water coming into contact with electrical devices is high. By monitoring the amount of current flowing through the circuit, GFCI outlets can quickly detect any imbalance that might indicate a ground fault, which could lead to serious electric shock or fire hazards.

This functionality makes option A the most appropriate choice, as it directly relates to the primary purpose of GFCI outlets: enhancing safety in wet environments. The other choices do not align with the specific protective function of GFCI outlets. For example, using GFCI outlets in hallways, bedrooms, or garages for convenience, comfort, or lighting does not address the need for shock protection in areas where water could cause hazards, which is the fundamental focus of GFCI installations.
