Answer: Amazon S3

Amazon S3 (Simple Storage Service) is the correct AWS service for this functionality because: - **Amazon S3** is an object storage service that allows you to store and retrieve any amount of data from anywhere on the web - It supports **public URLs** for direct file downloads when objects are made publicly accessible - You can configure S3 buckets and objects with public read permissions - Users can download files directly using URLs like: `https://bucket-name.s3.region.amazonaws.com/filename.ext` **Why other options are incorrect:** - **Amazon Redshift**: A data warehousing service, not designed for file storage with public URL access - **Amazon EBS**: Block storage service for EC2 instances, not accessible via public URLs - **Amazon EFS**: File storage service for EC2 instances, primarily for internal network access, not public URL downloads Amazon S3 is specifically designed for web-scale storage with HTTP/HTTPS access, making it ideal for serving files via public URLs.
