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.

I believe the answer is C.
HTTP 200 code successful put object and the following.
“To ensure that data is not corrupted traversing the network, use the Content-MD5 header. When you use this header, Amazon S3 checks the object against the provided MD5 value and, if they do not match, returns an error. Additionally, you can calculate the MD5 while putting an object to Amazon S3 and compare the returned ETag to the calculated MD5 value”
