Answer: C

Explanation:

ARP for IPv4 and Neighbor Discovery Protocol (NDP) for IPv6 are both used to map a device’s IP address to its MAC address. This is essential for communication within a local network.

ARP is used in IPv4 networks, and NDP performs a similar function in IPv6 networks, ensuring devices can communicate effectively on the same network segment.
