Final answer:
c) Unicast addressing allows hosts on a LAN to send traffic to remote networks. Hence, option c) is correct.
Step-by-step explanation:
The correct answer is Unicast addressing.
ARP (Address Resolution Protocol) is used to map an IP address to a MAC address on a local network. It allows hosts on a LAN to send traffic to remote networks by resolving the destination IP address to its corresponding MAC address.
When a host wants to send data to a remote network, it checks its ARP table to see if it already has the MAC address of the destination IP. If not, it sends an ARP request as a Unicast frame to the local network asking for the MAC address of the destination IP. The destination host then responds with its MAC address, allowing the original host to send the data.
