Why each option
This question asks to identify the protocol used to map a known IP address to its corresponding MAC address on a local network segment. ARP is the correct protocol for this address resolution.
DHCP (Dynamic Host Configuration Protocol) assigns IP addresses and other network configuration parameters to devices on a network.
ARP (Address Resolution Protocol) is a network layer protocol used to discover the MAC address associated with a given IP address on the same local network segment. When a device needs to send data to an IP address on its local network but only knows the IP, it sends an ARP request broadcast to resolve the destination's MAC address.
DNS (Domain Name System) resolves human-readable hostnames (like www.example.com) to IP addresses.
RARP (Reverse Address Resolution Protocol) resolves a known MAC address to an IP address, which is the inverse of what the question asks.
