Answer: Configure CORS on the central S3 bucket to enable access for the web applications.
The correct answer is C: Create a cross-origin resource sharing (CORS) configuration that allows access to the central S3 bucket and add the CORS configuration to the central S3 bucket. Web browsers implement the same-origin policy which restricts how resources can be fetched from another domain, affecting security. To allow your client-side web applications to load JavaScript files and web fonts from the central S3 bucket, you need to configure CORS on the S3 bucket to permit cross-origin requests. This allows the web applications hosted in different S3 buckets under different domains to access the centralized resources without being blocked by the browser.
