When a wireless client uses WPA2 AES, which keys are created at the end of the four-way handshake process between the client and the access point?

A.
AES key, TKIP key, WEP key

B.
AES key, WPA2 key, PMK

C.
KCK, KEK, TK

D.
KCK, KEK, MIC key

Explanation:
When WPA-PSK or WPA2-PSK is performed via Temporal Key Integrity Protocol (TKIP) or Advanced Encryption Standard (AES) for the encryption,
the client must go through the process known as the WPA 4-Way handshake for both the initial association and also when roaming. As previously explained, this is
basically the key management process used in order for WPA/WPA2 to derive the encryption keys. However, when PSK is performed, it is also used in order to
verify that the client has a valid Pre-Shared Key to join the WLAN.
