In the truth table of the above circuit, the value of and are:
Correct answer:C
Conflicting solution extraction
Given: The question asks for the values of and in the truth table of the above circuit.
Find: The correct ordered pair corresponding to and .
The solution is internally inconsistent and appears to describe two different circuits. In one extracted approach, the text concludes that and , and explicitly states that the correct answer is . A second extracted approach also concludes Option (1) with and for the circuit it describes.
However, the actual circuit diagram referred to by the words "above circuit" is not present in the given the question, so the circuit cannot be independently verified from the provided input. The answer key says (3) , but the solution points to Option A / Option (1).
Because the essential circuit diagram is missing and the extracted answer sources conflict, the correct option cannot be resolved with confidence from the provided material alone.
Ignoring the actual gate interconnections and evaluating gates in isolation is incorrect because the output depends on how intermediate outputs feed later gates. Always trace the circuit branch by branch from input to final output.
Trusting the answer key key without checking the worked solution can be wrong when provided pages contain mismatches. Compare the final conclusion in the solution with the listed answer and verify against the diagram.
Treating a missing circuit diagram as if the gate arrangement were obvious is incorrect. For logic-gate questions, the diagram is essential context; without it, outputs such as and may be impossible to determine uniquely.
