Step-by-step verified solution

Official answer: C) DHCP

DNS and HTTP

Let's analyze the purpose of each protocol:

DNS (Domain Name System): Resolves human-readable domain names (e.g., www.example.com) to IP addresses (and vice-versa via reverse DNS).
ARP (Address Resolution Protocol): Resolves network-layer IP addresses (logical addresses) to data-link layer MAC addresses (physical addresses).
RARP (Reverse Address Resolution Protocol): Resolves data-link layer MAC addresses (physical addresses) to network-layer IP addresses (logical addresses).
DHCP (Dynamic Host Configuration Protocol): Used to dynamically allocate/assign IP addresses, subnet masks, default gateways, and other configuration parameters to client hosts on a network. It does not map or resolve one existing form of address to another.

Therefore, DHCP is NOT used to resolve one address form to another.

Hence, the correct option is (C).
