B . CRC-MAC
C . CBC-MAC
D . CBC-32

Answer: C

Explanation:

The integrity check mechanism used by WPA2 to provide security against replay attacks is the Cipher Block Chaining Message Authentication Code (CBC-MAC). This mechanism is part of the protocol suite that ensures data integrity and authenticity by using a combination of cipher block chaining (CBC) and message authentication code (MAC) to produce a secure and unique code for each data packet.

Reference: This information is consistent with the security protocols outlined in WPA2 standards, which specify the use of CBC-MAC for integrity checks12.
