B Correct answer
Explanation

In IBM JCL (z/OS), relative generation numbers of a Generation Data Group (GDG) are resolved relative to the state of the GDG catalog at the beginning of the job. Therefore, a (+1) generation created in an early step must continue to be referenced as (+1) in subsequent steps of the same job.
