   What is a metamorphic relation in the context of testing AI systems?

   • AA property that must hold between the outputs of a source test case and a follow-up test case.
   • BA set of test cases that are executed in a specific order.
   • CA metric used to measure the accuracy of an AI model.
   • DA tool that automatically generates test cases for AI systems.

   A team is testing an AI system that predicts whether a student will pass an exam based on study hours and attendance. They define a metamorphic relation: increasing study hours should not decrease the predicted pass probability. They run multiple test cases. In one case, the source output is 0.8 and the follow-up output is 0.9. In another case, the source output is 0.6 and the follow-up output is 0.5. What is the most appropriate interpretation?

   • ABoth cases satisfy the relation because the probability did not decrease in either case.
   • BThe results are inconclusive because the relation is not applicable to probability outputs.
   • CThe first case satisfies the relation, but the second case violates it, indicating a potential defect.
   • DBoth cases violate the relation because the probability should always increase with study hours.

   When a metamorphic test passes, what can be concluded?

   • AThe system is completely defect-free.
   • BThe system's accuracy is high.
   • CThe system behaves as expected for the tested relation, but other defects may still exist.
   • DThe metamorphic relation is valid for all inputs.
