Final answer:
To provide a report on test case execution coverage of the requirements, the traceability between test cases and requirements needs to be tracked, typically using a traceability matrix. Option A is correct.
Step-by-step explanation:
To create a report showing test case execution coverage of the requirements, you need to track the traceability between the test cases and the requirements. This involves mapping each test case to one or more requirements to ensure that all requirements have been tested. It is essential to document which test cases cover which requirements, often in a traceability matrix. This allows stakeholders to verify that all functional and non-functional requirements have been considered in the test planning and execution phases. By doing this, you cannot only demonstrate the coverage of the test cases but also identify any gaps in the testing process that may need to be addressed.
