Explanation:

The AWS Documentation mentions the following

All objects by default are private. Only the object owner has permission to access these objects.

However, the object owner can optionally share objects with others by creating a pre-signed URL using their own security credentials, to grant time-limited permission to download the objects. Option A is invalid because this can be used to prevent accidental deletion of objects Option C is invalid because timestamps are not possible for Roles Option D is invalid because policies is not the right way to limit access based on time For more information on pre-signed URL's, please visit the URL:
