Explanation

The DD DISP parameter tells the system what to do with a dataset based on job step termination. It has three sub-parameters: status (describes dataset's current state like NEW, SHR, MOD), normal disposition (what to do on successful completion like KEEP, DELETE, CATLG), and abnormal disposition (what to do on failure like DELETE, KEEP, CATLG). Since it handles both normal and abnormal termination and describes status, 'All of the above' is correct.
