A Correct answer
Explanation

The arp -a command displays the ARP (Address Resolution Protocol) cache, which shows the MAC addresses of network devices that the system has recently communicated with. This is the standard way to view MAC addresses in the ARP table. Options with 'apr' are typos, and -vi is not the correct flag combination for displaying ARP information.
