A. Incorrect.

 

B. Which John? John the Baptist, of course. Jesus went out to the Jordan River to be baptized by his cousin. Before John, baptism in the Judaic tradition had to do with a newcomer to the faith washing away his or her uncleaness. With John, it was conversion, a turning from sin. And after him, when the Apostles baptized as jesus told them to, Baptism became necessary for salvation.
