B Correct answer
Explanation

JCL (Job Control Language) uses //* as the comment indicator. These characters must appear in columns 1-3 of the JCL card. The /* option is used for JES stream delimiters, not comments. //- and /-- are not valid JCL comment syntax.

AI explanation

In JCL, a comment statement is identified by placing //* in columns 1 through 3 of the card/line. This distinguishes it from a normal JCL statement (which starts with // followed by a name) and from a delimiter statement (/*). Comment cards are ignored by the JCL processor and used purely for documentation.
