To solve this question, the user needs to know about how to restart an abnormally terminated job.

Option A: Specify RESTART = STEPNAME in the JOB step.

This option is partially correct. In order to restart an abnormally terminated job, the RESTART parameter must be specified in the JOB statement. However, the value for RESTART should be the name of the step where the job should resume, not "STEPNAME".

Option B: Specify RESTART = Y in the JOB step.

This option is incorrect. There is no value of "Y" for the RESTART parameter. The valid values are the step name where the job should restart or "RESTART=NO" to prevent a job from being restarted.

Option C: Specify RESTART = N in the JOB step.

This option is incorrect. "N" is not a valid value for the RESTART parameter. The valid values are the step name where the job should restart or "RESTART=NO" to prevent a job from being restarted.

Option D: None of the above.

This option is incorrect. Option A is partially correct, but the other options are incorrect.

Option E: All of the above.

This option is incorrect. Option A is partially correct, but the other options are incorrect.

Therefore, the correct answer is:

The Answer is: A. Specify RESTART = STEPNAME in the JOB step.
