To answer this question, you need to understand the concept of verification and its benefits in the early stages of the life cycle.
Option A) It facilitates timely set up of the test environment - This option is incorrect because verification is not specifically related to setting up the test environment. Verification is the process of evaluating a system or component to determine whether it satisfies specified requirements.
Option B) It allows the identification of changes in user requirements - This option is correct. One of the major benefits of verification early in the life cycle is that it allows the identification of changes in user requirements. By verifying the requirements early on, any discrepancies or changes can be identified and addressed before the development process progresses further.
Option C) It reduces defect multiplication - This option is incorrect. While verification does contribute to reducing defects, it is not specifically related to defect multiplication.
Option D) It allows testers to become involved early in the project - This option is incorrect. While involving testers early in the project is beneficial, it is not the major benefit of verification.
The correct answer is B) It allows the identification of changes in user requirements. This option is correct because verification helps ensure that the requirements are accurately captured and understood, allowing any changes or discrepancies to be identified and addressed early in the life cycle.
