Explanation

Option A correctly distinguishes the two concepts: Confirmation testing (also called re-testing) verifies that a specific defect has been fixed by re-executing the test cases that originally exposed it, while Regression testing checks that the fix - or any other change - hasn't unintentionally broken something that was previously working.

Option B swaps the definitions, describing what Regression testing does but incorrectly attributing it to Confirmation testing. Option C wrongly claims both serve the same purpose (detecting newly introduced defects), which erases the distinction between them. Option D wrongly claims both are about retesting known fixes, ignoring Regression testing's broader safety-net role.

Memory tip: Think Confirmation = Check the fix (did this bug go away?), and Regression = Ripple check (did fixing this break anything else?).
