Selected Answer: B
B. Receiving station's output power CHAPTER 2 - PAGE 77 (Official Study Guide) --> This page tells us a little about it. The output power generated by the RECEIVING station does not interfere with the power it is receiving. FYI: "Free Space Path Loss (FSPL), [...] is a weakening of the RF signal due to a broadening of the wave front."

Receiver sensitivity defines the minimum signal strength at which a data rate can be correctly received by a STA. RF sensitivity thresholds indicate lower limit of received power required to support operations. In WLANs, sensitivity thresholds indicate lower limit of received power required to support Dynamic Rate Shifting (DRS) levels and modulations.

I too agree. If receiver sensitivity is not good, when signal is weak, receiver won't be able to pick the signal at all. So, I too think, it should be B.

This has to be B, because all other answers influence the distance.
