Correct answer: C
Key idea: Resolving addresses means translating between different address forms (for example, hostname ↔ IP or IP ↔ MAC).
DNS: Translates domain names (hostnames) to IP addresses. Reverse DNS (PTR records) can map IP back to a name.
ARP: Maps IPv4 addresses to MAC (link-layer) addresses on a local network (IP → MAC).
RARP: Historically mapped a MAC address to an IP address (MAC → IP).
DHCP: Assigns IP addresses and other network configuration to hosts (leases/configuration). It does not perform translation between different address forms.
Conclusion: DHCP is not used to resolve one form of address to another; it provides address assignment and configuration rather than address-to-address translation.
