Confirmation testing is performed after a defect is fixed, and if such testing is successful then the regression tests that are relevant for such fix can be executed. Confirmation testing, also known as re-testing, is the process of verifying that a defect has been resolved by running the test case that originally detected the defect. Confirmation testing is usually done before regression testing, which is the process of verifying that no new defects have been introduced in the software as a result of changes or fixes. Therefore, option D is the correct answer.

Test automationimproves efficiency and accuracy, butit does NOT eliminate manual testing (D).

(A) is correctbecause automationspeeds up execution.

(B) is correctas automated tests produceconsistent and unbiased results.

(C) is correctbecause automationreduces human errors in repetitive tests.

However,manual testing remains essential for exploratory testing, usability testing, and complex test scenarios.

Debugging activities typically include reproducing the failure, diagnosing the root cause, and fixing the cause of the failure. Adding new test cases, while important in the overall testing process, is not a direct part of debugging. Debugging focuses on understanding and correcting the issue that caused the failure, rather than expanding the test suite.
