Suggested Answer: D

In maintenance testing, the relationship between impact analysis and regression testing is that the impact analysis is used to evaluate the amount of regression testing to be performed. Maintenance testing is a type of testing that is performed on an existing software product after it has been delivered or deployed, in order to ensure that it still meets its requirements and functions correctly after a change or a modification. Maintenance testing can be triggered by various reasons, such as corrective maintenance (fixing defects), adaptive maintenance (adapting to new environments), perfective maintenance (improving performance), preventive maintenance (avoiding future problems), etc. Impact analysis is a technique that is used to assess the extent and nature of changes introduced by maintenance activities on the software product or project. Impact analysis helps to identify which parts of the software product are affected by the changes, which parts need to be modified or updated accordingly, which parts need to be retested or verified for correctness or compatibility, etc. Regression testing is a type of testing that verifies that previously tested software still performs correctly after a change or a modification. Regression testing helps to detect any side effects or unintended consequences of maintenance activities on the software product's functionality or quality. Regression testing can be performed at various levels and scopes depending on the impact analysis results. Therefore, in maintenance testing, impact analysis is used to evaluate the amount of regression testing to be performed.

Option B is tempting, but I think option C is the clear winner here. Regression testing is all about verifying existing functionality, not testing new features.

Haha, option V is just plain silly. Tests that are only used once? That's not how regression testing works at all!

I agree, option V is misleading. It's important to focus on retesting fixed defects and testing already tested programs during regression testing.

Option V is definitely not correct. Regression testing is all about retesting to ensure that previously working functionality still works after changes.

I disagree with option V. Regression tests must be repeatable to ensure consistent results and validate that no regressions have occurred.
