actions on that bucket or object.

A.
a file

B.
a bucket or object

C.
a bucket or file

D.
a object or file

Amazon S3 doesn’t automatically give a user who creates a bucket or object permission to
perform other actions on that bucket or object. Therefore, in your IAM policies, you must
explicitly give users permission to use the Amazon S3 resources they create.
