Which designation corresponds to a plenum-rated Ethernet cable?

Explanation:
Plenum-rated cables are designed for spaces that handle air flow, like drop ceilings and air ducts, where smoke would spread quickly in a fire. The jacket is built to minimize smoke and toxic fumes and to meet safety tests mandated by building codes. This is why the designation that explicitly indicates this safety attribute is “Ethernet (Plenum)”—it tells you the cable is approved for use in plenums. The other options specify data performance (Cat 7, Cat 6, Cat 5e) and describe speed or category, but they do not inherently convey the fire/smoke safety requirement for air‑handling spaces.
