What correctly describes the Pairwise Master Key (PMK) in thee specified wireless security protocol?

In WPA3-Enterprise, the Pairwise Master Key (PMK) is indeed unique for each session and is derived using a process called Simultaneous Authentication of Equals (SAE). SAE is a new handshake protocol available in WPA3 that provides better security than the Pre-Shared Key (PSK) used in WPA2. This handshake process strengthens user privacy in open networks and provides forward secrecy. The information on SAE and its use in generating a unique PMK can be found in the Wi-Fi Alliance's WPA3 specifications and related technical documentation.
