Matching Column A Column B A. AND I. output 1 only if both input 1 B. OR II. output 1 if any input 1 C. NAND III. output 0 only if both input 1 D. NOR IV. output 1 only if both input 0

(A)-I, (B)-II, (C)-III, (D)-IV Explanation: Solution A. AND Gate: The output is high ( ) only when all its inputs are high. If any input is , the output is . Matches with: I B. OR Gate: The output is high ( ) if at least one of the inputs is high. It only outputs when all inputs are . Matches with: II C. NAND Gate: This is the complement of the AND gate. It outputs a low ( ) only when both inputs are high ( ). For all other input combinations, the output is . Matches with: III D. NOR Gate: This is the complement of the OR gate. It outputs a high ( ) only when both inputs are low ( ). If any input is , the output becomes . Matches with: IV Conclusion The correct mapping is (A)-I, (B)-II, (C)-III, (D)-IV . The correct option is (c) .
