ARP is used to bind which addressing schemes?

Explanation:
ARP maps an IP address to a MAC address on the local network. When a host wants to send an IPv4 packet to another device on the same LAN, it needs the destination’s MAC to build the Ethernet frame. If the MAC isn’t known, the host broadcasts an ARP request asking who has that IP, and the device with that IP responds with its MAC. This resolves the address at Layer 2 so the frame can be delivered within the local broadcast domain. The other options describe DNS (IP to hostname), VLAN mappings (MAC to VLAN), or IP/subnet concepts, which are not what ARP performs.
