B Correct answer
Explanation

When a GDG generation is created with gdgname(+1) in Step 1, it becomes the current generation. In subsequent steps, you reference it as gdgname(0), which always points to the most recent generation. The (+1) notation creates a new generation, while (0) references the existing one.
