Which of the following is a location where a plenum cable is recommended?

Answer options

• A. Frequently traveled areas
• B. Outdoor environments
• C. Inside conduits
• D. Airspaces above a ceiling

Correct answer: D

Plenum cables are specifically designed to be used in airspaces above ceilings because they have a low smoke and flame rating, making them safer in the event of a fire. The other options do not provide the necessary safety features required for areas with air circulation and potential fire hazards.
