Suppose that in an IP-over-Ethernet network, a machine X wishes to find the MAC address of another machine Y in its subnet. Which one of the following techniques can be used for this?

A. X sends an ARP request packet to the local gateway’s IP address which then finds the MAC address of Y and sends to X

B. X sends an ARP request packet to the local gateway’s MAC address which then finds the MAC address of Y and sends to X

C. X sends an ARP request packet with broadcast MAC address in its local subnet

D. X sends an ARP request packet with broadcast IP address in its local subnet

C. X sends an ARP request packet with broadcast MAC address in its local subnet

X sends an ARP request packet with broadcast MAC address in its local subnet
