Explanation

Regression testing (or a regression plan) verifies that a change has not broken or degraded existing functionality that was previously working. It is the most targeted response when you are specifically concerned about a change damaging key functionality. A quality control check (A) is broader and less focused on change impact. An impact evaluation (B) is valuable but comes before testing. Software version control (C) manages code history but does not validate functional integrity after a change.
