The correct answer is D. Create the traceability between the test cases and the requirements. This is because traceability is the ability to follow the life of a requirement, in both a forward and backward direction, through its documentation, development, and testing. Traceability can help to ensure that the test cases are derived from the requirements, and that they cover all the relevant aspects of the system. By creating the traceability between the test cases and the requirements concurrently with creating the test cases, the test team can improve the quality and completeness of the test design, and facilitate the test analysis and reporting.

A static analysis tool is a software tool that analyzes the source code of a program without executing it. It can detect various software characteristics, such as syntax errors, potential bugs, security vulnerabilities, code quality, and coding standard violations. Coding standard violations are deviations from the agreed or recommended rules and conventions for writing source code, such as naming, indentation, formatting, commenting, and complexity. A static analysis tool can check the source code against a predefined or customized coding standard and report any violations. Coding standard violations can affect the readability, maintainability, and portability of the code, and can also introduce defects or inconsistencies.

The graph indicates that a significant portion of risks, 29%, have not been mitigated, which suggests that these are either failed tests or other discovered failures. This level of unmitigated risk puts the project at risk, as it implies that there are still substantial issues that need to be addressed.
Reference:
The ISTQB Advanced Level Test Manager documents outline the importance of risk-based testing and the interpretation of residual risk graphs. These graphs are used to communicate the current status of risk mitigation efforts in the project, and a high percentage of unmitigated risks is a clear indicator of potential problems1.
