What happens to line numbers after deleting a step?

When a step is deleted in a sequence of instructions or programming, it creates a gap where that step previously existed. In order to maintain the continuity and logical flow of the remaining instructions, all line numbers that come after the deleted step need to be adjusted. This means that each line number below the deleted line is renumbered to reflect its new position in the sequence.

For example, if line 10 is deleted, the next line, which was numbered 20, would be renumbered to 10 to fill the void created by the deletion. This renumbering ensures that there are no missing references in the flow of instructions, making programming or instruction execution more seamless. Option C correctly describes this behavior, which is a standard practice in programming and scripting environments.

While other options may touch on related outcomes, they do not accurately reflect the process of renumbering that occurs below the deleted address.
