Explanation: Your answer is incorrect
Answer-A
Such a scenario is also given in the IAM Documentation Cross-Origin Resource Sharing: Use-case Scenarios
The following are example scenarios for using CORS:
• Scenario 1: Suppose that you are hosting a website in an Amazon S3 bucket named website as described in Hosting a Static Website on Amazon S3. Your users load the website endpoint http://website.s3-website-us-east-1 .amazonIAM.com. Now you want to use JavaScript on the webpages that are stored in this bucket to be able to make authenticated GET and PUT requests against the same bucket by using the Amazon S3 API endpoint for the bucket website.s3.amazonIAM.com. A browser would normally block JavaScript from allowing those requests, but with CORS you can configure your bucket to explicitly enable cross-origin requests from website.s3-website-us-east-1 .amazonIAM.com.
• Scenario 2: Suppose that you want to host a web font from your S3 bucket. Again, browsers require a CORS check (also called a preflight check) for loading web fonts. You would configure the bucket that is hosting the web font to allow any origin to make these requests.
Option Bis invalid because versioning is only to create multiple versions of an object and can help in accidental deletion of objects
Option C is invalid because this is used as an extra measure of caution for deletion of objects
Option D is invalid because this is used for Cross region replication of objects

The correct answer is: Enable CORS for the bucket
