The correct answer is B, Amazon CloudFront. Amazon CloudFront is a content delivery network (CDN) service provided by AWS. It is specifically designed to deliver static and dynamic web content with low latency. This is achieved by distributing the content across a global network of edge locations. When a user requests content, CloudFront serves it from the edge location closest to the user, which reduces the distance and time it takes for the content to be delivered. This results in a faster and more efficient delivery of content, improving the overall user experience. The other options, AWS Lambda, Amazon EC2 Auto Scaling, and AWS Compute Optimizer, are not designed for content delivery and do not provide the same low-latency benefits as Amazon CloudFront.
