Selected Answer: C
By default, all Amazon S3 objects are private, only the object owner has permission to access them. However, the object owner may share objects with others by creating a presigned URL. A presigned URL uses security credentials to grant time-limited permission to download objects. The URL can be entered in a browser or used by a program to download the object. The credentials used by the presigned URL are those of the AWS user who generated the URL.
