B Correct answer
Explanation

In JCL, the RD (Restart) parameter controls automatic job restart after system failures. RD=NC (No Check) means automatic and deferred restart are disabled - the job will not restart under any circumstances without manual intervention.

AI explanation

The RD (restart) parameter on a JOB or EXEC statement controls whether automatic step restart and/or deferred restart are allowed after an abend. RD=NC specifically means "no checkpoint," which disables both automatic restart and deferred (checkpoint) restart entirely, so no restart of any kind can occur for that job or step.
