D. Would be acceptable is the point was to redirect to an on premises DNS server No need for VPN as VPC Peering is a lot simplier The wording of the question is atrocious, but that leaves only A and Cas plausible answers

A. Peer the VPCs and set up routes between them. C. Configure DHCP option sets in both VPCs to point to the DNS server. If you would like to use Route53, it must be Route53 Inbound Resolver Configuration
