Answer: AE

Explanation:

the Rapid Commit option is used to indicate the use of the two-message exchange for address assignment.

The code for the Rapid Commit option is 80. The format of the option is:

Code Len

A client MUST include this option in a DHCPDISCOVER message if the client is prepared to perform the DHCPDISCOVER-DHCPACK message exchange described earlier.

A server MUST include this option in a DHCPACK message sent in a response to a DHCPDISCOVER message when completing the DHCPDISCOVER-DHCPACK message exchange.
