C for sure

in my opinion the difference between A and C isn't the BGP, but the static route.if you advertise a default route to AWS, then all the traffic will go throuth DX.

C. Create a public interface on your AWS Direct Connect link. Redistribute BGP routes into your existing routing infrastructure; advertise specific routes for your network to AWS.

The correct option is: C. Create a public interface on your AWS Direct Connect link. Redistribute BGP routes into your existing routing infrastructure; advertise specific routes for your network to AWS. This setup allows you to access AWS public services such as S3 over Direct Connect by using a public interface, while other Internet traffic continues to utilize the standard ISP link. Configuring BGP to only advertise specific routes necessary for AWS ensures that only the desired traffic to AWS services travels over Direct Connect.

keyword = public virtual interface && BGP then C

C is correct as we need to use public VIF on direct link to connect to S3. BGP protocol is used for dynamic, hence option A is eliminated.
