Cyclomatic complexity is a measure of the number of linearly-independent paths through a program's source code, which is often used as a measure of the complexity of a program. The control flow graph provided represents the logic of a software component and has more than 5 nodes with decision points, indicating that the complexity would exceed the maximum allowed value of 5. The calculation for cyclomatic complexity is V(G) = E - N + 2P, where E is the number of edges, N is the number of nodes, and P is the number of connected components. In this case, the calculated cyclomatic complexity exceeds the allowed threshold, thus a defect should be reported.

For a Medium risk mission- or safety-critical system, the best testing approach includes a combination of automated tests, exploratory tests, and manual black-box tests. Option B is the most comprehensive, advocating for automated tests to ensure reliability and repeatability, highly recommending exploratory tests to cover unforeseen scenarios, and recommending manual black-box tests to cover standard use cases. This multifaceted approach ensures thorough testing coverage essential for medium risk, safety-critical systems​​.

Static analysis is used on an Agile project to identify the causes of technical debt through the use of tools. This approach allows teams to detect potential issues in code that could lead to technical debt if not addressed promptly, thus maintaining the health of the codebase as it evolves rapidly in Agile environments .
