Using a Multi-region Accesspoint in an Active-Active setup will send data to the closest Region, without accessing the internet: "send remote user data to the nearest S3 bucket with no public network congestion" Not very easy to read and understand but it's all there: https://docs.aws.amazon.com/AmazonS3/latest/userguide/MultiRegionAccessPoints.html

D. Set up Amazon S3 to use Multi-Region Access Points in an active-active configuration with a single global endpoint. Configure S3 Cross-Region Replication.

D is correct

Answer D https://docs.aws.amazon.com/AmazonS3/latest/userguide/MultiRegionAccessPoints.html When you create a Multi-Region Access Point, you specify a set of AWS Regions where you want to store data to be served through that Multi-Region Access Point. You can use S3 Cross-Region Replication (CRR) to synchronize data among buckets in those Regions. You can then request or write data through the Multi-Region Access Point global endpoint. Amazon S3 automatically serves requests to the replicated dataset from the closest available Region. Multi-Region Access Points are also compatible with applications that are running in Amazon virtual private clouds (VPCs), including those that are using AWS PrivateLink for Amazon S3. https://docs.aws.amazon.com/AmazonS3/latest/userguide/replication.html

To me it looks like C, the requirement is to send the request to the closest region
