D Correct answer
Explanation

In JCL, operations must be followed and preceded by at least one blank (D is true) for proper parsing. Statement A is false - DD statements can precede EXEC statements in certain contexts like instream procedures. Statement B is false - 'JOB' is not an OPERATION keyword (it's a statement). Statement C is false - JCL operations cannot extend beyond position 72 as that's the record boundary.
