   A test analyst is evaluating a legacy function with a cyclomatic complexity of 15. The team has limited testing time and must prioritize which functions to test first. What is the most appropriate interpretation of this complexity value?

   • AThe function is simple and requires minimal testing effort
   • BThe function should be rewritten because it is too complex to test
   • CThe function has exactly 15 defects that need to be fixed
   • DThe function has 15 independent paths that should be tested, indicating high complexity and testing effort

   • B6
   • C5
   • D4

   What is an independent path in a control flow graph?

   • AA path that does not share any nodes with other paths
   • BA path that is the shortest route from start to end
   • CA path that introduces at least one new edge not previously traversed
   • DA path that has no loops or cycles

   What does cyclomatic complexity measure in a program?

   A development team is adopting basis path testing for a critical module. The test manager asks the test analyst to explain the primary benefit of this technique over simple statement coverage. What is the most accurate response?

   • ABasis path testing eliminates the need for any other testing techniques
   • BBasis path testing ensures that every independent path through the code is executed at least once
   • CBasis path testing automatically fixes defects found during test execution
   • DBasis path testing guarantees the absence of all defects in the tested code
