Explanation
Option A correctly configures the NAT interfaces: Gig0/0 (facing the internal FTP servers at 10.10.110.x) is set as 'ip nat inside', and Gig0/1 (facing the NAT Router at 12.16.1.x) is set as 'ip nat outside'. Option C correctly implements destination NAT load balancing using 'ip nat inside destination-list' with 'type rotary', which is the Cisco IOS keyword required to enable round-robin load balancing across a pool of real servers when traffic destined for a virtual IP (10.10.110.10) arrives from the outside.
