C is right This solution will ensure interoperability among the VPC hosted services and the AWS Marketplace partner service while avoiding any IP address conflicts. By using AWS PrivateLink, both VPCs can connect directly to the partner service without exposing their private IP addresses to the internet. The interface endpoints created for each VPC will have unique, private DNS names that can be used to route traffic between the VPCs and the partner service. This solution does not require any additional network configurations or routing changes, as traffic will be automatically routed through AWS PrivateLink.

C is right! A. VPC peering does not support overlapping IP address ranges. B. A transit gateway does not resolve IP overlap issues. The partner service requires a direct interface endpoint (e.g., via PrivateLink) rather than routing through NAT gateways. D.NAT instances do not solve the overlapping IP address problem between VPCs.

Since the ips are overlapping, VPC peering is out and also TGW is also. Nat instance option is not preferred when you considered IP overlaps. Hence C is the correct answer

Absolutely C

this is C
