Why each option

The Address Resolution Protocol (ARP) is the protocol responsible for converting a logical IP address into a physical MAC address within a local network segment.

AIPSEC

IPSEC (Internet Protocol Security) is a suite of protocols for securing IP communications, not for IP to MAC address resolution.

BARPCorrect

ARP (Address Resolution Protocol) is a crucial protocol in the TCP/IP suite that maps IP network addresses to the hardware (MAC) addresses used by a data link protocol. When a device needs to communicate with another device on the same local network and only knows its IP address, ARP is used to discover the corresponding MAC address.

CDARP

DARP is not a standard protocol for IP to MAC address resolution; ARP is the fundamental protocol.

DDNS

DNS (Domain Name System) resolves human-readable hostnames to IP addresses, not IP addresses to MAC addresses.

ENone of the above

ARP is the correct protocol, so this option is incorrect.
