B Correct answer
Explanation

A (+1) generation dataset created in an earlier step of the same job can be referenced as (+1) in subsequent steps. This relative generation notation allows you to reference the newly created generation without knowing its absolute generation number. The system tracks the generation reference within the job's execution context.

AI explanation

When a new generation of a GDG (Generation Data Group) is created in one step of a job, the catalog isn't updated with the new absolute generation number until the job completes. So within the same job, later steps must still reference it by the relative generation number used to create it, i.e. (+1), not (0), since (0) would still point to the prior current generation.
