The best solution is to: (B) Set up an S3 bucket in us-east-1 with Cross-Region Replication from the primary S3 bucket in eu-west-1. This brings the data physically closer to the new users. (D) Use Lambda@Edge to route requests from North America to the us-east-1 S3 bucket, reducing latency and improving performance. This combination avoids invalid services (like Global Accelerator for S3) and leverages CloudFront and regional S3 data for optimal speed and availability.v
Although, D is not really correct. You should be using "s3 multi-region access point". It is designed specifically for this scenario.
The correct answer implies a CloudFront with multiple origins, i.e. pointing to two (2) S3 buckets and using Lambda@Edge to decide which origin to go to.
