what is the indication that an object was successfully stored?

When you put objects in Amazon S3, what is the indication that an object was successfully stored?

A.
Each S3 account has a special bucket named_s3_logs. Success codes are written to this bucket with a
timestamp and checksum.

B.
A success code is inserted into the S3 object metadata.

C.
A HTTP 200 result code and MD5 checksum, taken together, indicate that the operation was successful.

D.
Amazon S3 is engineered for 99.999999999% durability. Therefore there is no need to confirm that data was
inserted.
