Show answer and explanation

Correct answer: (C) DHCP

Explanation

DHCP commonly uses broadcast messages such as DHCPDISCOVER and DHCPREQUEST because a host may not yet know the address of the DHCP server when it boots. SMTP, FTP, and HTTP do not normally require broadcast in this way. Therefore, option (C) is correct.
