It's used in air circulation spaces, super important for safety!

I’m not entirely confident, but I think plenum-rated means it can handle higher temperatures? Could that be why it’s not for outdoor use?

I feel like I’ve seen a question like this before, and it was definitely about fire resistance. B seems to fit best.

I remember something about plenum-rated cables being used in ceilings or walls, but I’m not completely sure if it’s just for air circulation.

I think plenum-rated cable is related to fire safety, maybe for spaces where air circulates? So, B sounds right.
