A
Correct Answer
A technique that introduces small deliberate changes ("mutants") into the code and checks whether the existing tests fail, measuring the effectiveness of the test suite
Explanation
If a mutant survives (tests still pass despite the code change), it suggests the test suite has a gap in detecting that kind of fault, unlike code coverage which only shows whether code ran.
