To answer this question, let's go through each option to understand why it is correct or incorrect:
Option A) Indicates a new dataset and allocated, to CATLG the dataset if the step is successful and to delete the dataset if the step abends.
This option is incorrect. The correct disposition would be to catalog the dataset if the step is successful, not to allocate and catalog it.
Option B) Indicates a new dataset and needs to be allocated, to CATLG the dataset if the step is unsuccessful and to delete the dataset if the step abends.
This option is incorrect. The correct disposition would be to delete the dataset if the step abends, not if it is unsuccessful.
Option C) Indicates a new dataset and needs to be allocated, to CATLG the dataset if the step is successful and to delete the dataset if the step abends.
This option is correct. The disposition (NEW,CATLG,DELETE) indicates that the dataset is new and needs to be allocated. If the step is successful, the dataset should be cataloged. If the step abends (fails), the dataset should be deleted.
Option D) Indicates a new dataset and allocated, to CATLG the dataset if the step is unsuccessful and to delete the dataset if the step not abends.
This option is incorrect. The correct disposition would be to delete the dataset if the step abends (fails), not if it doesn't abend.
The correct answer is C. This option is correct because it accurately describes the disposition (NEW,CATLG,DELETE) as indicating a new dataset that needs to be allocated. If the step is successful, the dataset should be cataloged, and if the step abends (fails), the dataset should be deleted.
