The IEEE 802.11 standard (as amended) specifies two protection mechanisms: RTS/CTS and CTS-to-Self. Which statement is true regarding use of these two protection mechanisms?

A.
RTS and CTS frames use Short Interframe Spaces (SIFS), and CTS-to-Self frames use PCF Interframe Spaces (PIFS).

B.
Use of RTS/CTS introduces more latency than CTS-to-Self due to a higher number of frames transmitted onto the wireless medium.

C.
RTS and CTS frames get relayed through the access point, whereas the CTS-to-Self frames do not.

D.
A CTS-to-Self frame sent by a client station may reach fewer nodes than the RTS/CTS frame exchange.

E.
All client stations in a basic service area (BSA) hear RTS, CTS, and CTS-to-Self frames, so either the RTS/CTS mechanism or CTS-to-Self mechanism can be used with equal effectiveness.
