The correct choice indicates that a receptacle is indeed required within 25 feet of an air-conditioning unit. This requirement is in accordance with the National Electrical Code (NEC), which outlines specific safety and accessibility standards for electrical installations. Having a receptacle in close proximity to air-conditioning units facilitates easier access for plugging in the unit and ensures that maintenance personnel can operate the unit safely.

This also helps prevent the use of extension cords, which can pose a fire hazard if not rated or used properly. The specific distance of 25 feet is important because it strikes a balance between accessibility for service and maintaining a clean, organized workspace free from hazards.

The other options do not meet the safety and accessibility standards established by the NEC for air-conditioning units. If the distance were greater than 25 feet, it could make maintenance more difficult and increase the risk of unsafe working conditions.
