   Which of the following best describes Modified Condition/Decision Testing (MC/DC)?

   • AA technique that requires testing all possible combinations of conditions in a decision
   • BA black-box technique that tests the system's behavior without looking at the code
   • CA technique that only requires each condition to be true at least once
   • DA white-box technique that requires every condition in a decision to be shown to independently affect the decision's outcome

   What does it mean for a condition to 'independently affect' a decision's outcome in MC/DC?

   • AThe condition is true in all test cases
   • BChanging the condition's value alone can change the decision's outcome, while all other conditions remain fixed

   A test analyst is evaluating coverage reports for a module with a single decision `if (A || B)`. The report shows 100% condition coverage but only 50% MC/DC coverage. What does this indicate?

   • AEach condition has taken both true and false values, but the independent effect of each condition on the decision outcome has not been fully demonstrated.
   • BThe code contains a logic error that prevents MC/DC from being achieved.
   • CThe decision has not been executed at all.
   • DThe test cases are insufficient to cover all branches of the decision.
