ANo defect needs to be reported since the cyclomatic complexity of the component is calculated at 3.

BNo defect needs to be reported since the cyclomatic complexity of the component is calculated at 4

CNo defect needs to be reported since the cyclomatic complexity of the component is calculated at 5.

Show Suggested Answer

Suggested Answer: C

Static analysis is the best technique for identifying the root causes of issues in a legacy system where small functional enhancements take disproportionately long to implement. This technique involves examining the code without executing it to detect potential vulnerabilities, coding errors, and complexities. Static analysis can highlight problematic code segments and inefficient coding practices that may contribute to the increased time required for implementing changes, thereby assisting in addressing these systemic issues efficiently.

Okay, let me get this straight - the component is too complex, but they're saying it's not a defect? I think the car navigation system just wants to take a few wrong turns, that's all. D is the right choice.

But the maximum allowed cyclomatic complexity is 5, so D seems to be the right choice.
