Question 359Electricity & Electronics - Assistant Engineer

The correct answer is B) NAND gate. The four diagrams in the illustration EL-0233 represent the truth table and logic symbol of a NAND gate, which is a fundamental logic gate in digital electronics. A NAND gate produces a LOW (0) output only when all its inputs are HIGH (1), and a HIGH (1) output otherwise. This behavior is consistent with the truth table and logic symbol shown in the diagrams. The other answer choices are incorrect because they represent different types of logic gates with distinct input-output relationships. For example, an AND gate produces a HIGH output only when all its inputs are HIGH, while an OR gate produces a HIGH output when any of its inputs are HIGH.
