It prevents man-in-the-middle attacks.

B.
Replay protection is disabled.

Out-of-order frames are dropped.

D.

Explanation:
Replay protection. You can configure MACsec window size, as defined by the number of
out-of-order frames that are accepted. This value is used while installing the security associations
in the MACsec. A value of 0 means that frames are accepted only in the correct order.
Enable replay protection, and configure the window size in number of frames. The range
is from 0 to 4294967295. The default window size is 0.
Entering a window size of 0 is not the same as entering the no replay-protection command. Configuring a window size of 0 uses replay protection with a strict ordering of
frames.
Entering no replay-protection turns off MACsec replay-protection.
