Answer - C - In an 802.11g network that has the protected mode enabled, AP using CTS-to-Self and stations using RTS/CTS provides the best throughput with the least likelihood of retransmissions.

Key Takeaway: Because all stations in a BSS are able to hear the AP, CTS-to-Self is the most efficient method for the AP to perform NAV distribution. It is possible for two stations to be hidden from each other while both are part of the same BSS. In this case, RTS/CTS is the best method for performing NAV distribution.
