                     -- Answer: a) baptism --

          Though many people believe that it is merely some
     type of "spiritual baptism" -- apart from the water -- which
     saves, Paul shows that the baptism involved is one in which
     a person can be buried in and raised up from -- water
     baptism.  And that one is raised up from this baptism in
     order to be with Christ.

          As Paul also shows in Romans 6:3,4, one is raised up
     from water baptism to "walk in newness of life."
