Answer is C guys, have a look at this diagram https://docs.aws.amazon.com/Route53/latest/DeveloperGuide/resolver.html and read the steps below. Outbound is when the AWS Infra is communicating to On-prem (via the resolver). Inbound is when on-prem is communcating with AWS Infra!

A Inbound endpoints are used to forward DNS queries from your network to Route 53 Resolver within your VPC. They specify the IP addresses that DNS resolvers on your network should forward DNS queries to. This is the opposite of what the scenario requires. The scenario involves resolving DNS queries originating from an Amazon EC2 instance within a VPC. Therefore, the correct approach is to configure outbound forwarding, not inbound forwarding. Option A correctly describes the solution by suggesting the creation of an outbound endpoint and adding a forwarding rule for the domain example.com to forward DNS queries from the VPC to DNS resolvers on the network.
