B Correct answer
Explanation

When a GDG version is created with (+1) in a step, that version becomes the current generation (0) for subsequent steps. To reference the newly created version in Step 2, you use gdgname(+1) again - this resolves to the version just created in Step 1. Using (0) would reference the previous generation before Step 1 executed.
