Plenum cable is specifically designed for use in spaces where air circulation for heating and air conditioning systems occurs, known as plenums. This type of cable has a fire-retardant sheath to minimize the release of toxic fumes in the event of a fire, which is critical for safety in these environments.

Using plenum-rated cable ensures compliance with building codes and safety standards that govern installations in air-handling spaces. It is constructed to be low-smoke and flame-resistant, ensuring that if a fire were to occur, the cables would contribute minimally to the spread of flames and smoke. General-purpose cables and riser cables do not have the same fire-resistance properties and should not be used in plenum spaces due to the risk they pose in terms of fire safety.

Thus, the requirement for installation in a plenum area specifically points to the need for plenum-rated cable, making it the correct choice in this context.
