Explanation
In VRRP, the virtual IP (VIP) can be identical to one of the real interface IP addresses in the VRRP group - this router is called the IP Address Owner. When a router's physical interface IP matches the virtual IP, it automatically assumes the Master role with the highest possible priority (255), making the service IP and VIP one and the same. Option B is wrong because VRRP explicitly supports and defines this owner scenario - it is not a misconfiguration but a deliberate, valid design choice.
Memory tip: Think "owner = identical" - the router that owns the VIP literally has that address on its interface, so service IP = virtual IP is not just possible, it's a named VRRP concept.
