Which of the following is a requirement for receptacles in kitchens?

Receptacles in kitchens are required to be Ground Fault Circuit Interrupter (GFCI) protected if they are installed in areas near sinks. This is essential due to the increased risk of electrical shock in areas where water is present. GFCI protection is designed to cut off electrical power when it detects an imbalance in the electrical current, which can happen if water or moisture is involved, thereby providing additional safety for users.

In comparison, placing receptacles in a cupboard is not a practical safety measure because it would not allow for easy accessibility for appliances and would discourage proper usage. The requirement is that multiple receptacles should be installed within kitchens to ensure convenience and utility for numerous appliances, rather than limiting it to just one receptacle. Furthermore, while receptacles may be installed on exterior walls, this is not a specific requirement, as they can also be located in other areas according to the layout and design of the kitchen.
