802.11k Neighbor Requests and Neighbor Reports are sent in Action frames.

An Action frame consists of a Category field that indicates the type of action being performed, and a variable-length Action Details field that contains specific information related to the action. For example, an Action frame with a Category field value of 5 indicates a Radio Measurement action, and the Action Details field may contain a Neighbor Request or a Neighbor Report subelement .

Wait, is this a trick question? What if the answer is actually PSDU, just to mess with us?

PPDU sounds like the most logical choice here. The PHY layer is definitely responsible for framing the data.

Yes, PPDU is the right choice. It's important for the PHY layer to add framing to the data for transmission.

I think PPDU is the correct answer too. It makes sense that the PHY layer would create the Physical Protocol Data Unit.

But the PHY layer adds a header to create a Physical Layer Convergence Protocol Data Unit (PPDU), so I think the answer is D) PPDU.
