Explanation

Option A correctly captures the division of labor between VRRP roles: the Master is the active router that owns the virtual IP and MAC address, so it must respond to ARP requests and forward traffic destined for that virtual MAC - this is how end hosts seamlessly reach the default gateway. The Backup router stays passive; it deliberately ignores ARP requests for the virtual IP and discards packets addressed to the virtual MAC, because acting on them would create a conflict with the Master and break network traffic flow. Options B, C, and D are empty and therefore cannot describe any valid working mechanism, making A the only possible correct answer.

Memory tip: Think of the Master as "on duty" and the Backup as "standing by silently." The Master speaks (ARP replies, packet forwarding); the Backup watches but says nothing until the Master fails.
