   In a large automotive project, a defect is found during system testing that is traced back to a component-level issue. The component was tested by the software developer, and the system test was executed by a test engineer. According to best practices for roles and responsibilities, what should happen next?

   • AThe defect is logged and the system test is considered complete.
   • BThe software developer fixes the component, and the test engineer re-runs the system test after the fix.
   • CThe test engineer fixes the component and re-runs the system test.
   • DThe software developer re-runs the system test after fixing the component.
