The correct Answer is:
To solve the question, we need to analyze both the assertion and the reason provided. ### Step 1: Understand the Assertion The assertion states that the logic gate `NOT` can be built using a diode. A NOT gate, also known as an inverter, takes a single input and produces an output that is the logical negation of the input. ### Step 2: Evaluate the Assertion While it is true that diodes can be used in various logic circuits, they cannot function as a NOT gate by themselves. A NOT gate requires a component that can invert the signal, which diodes cannot do due to their unidirectional nature. Therefore, the assertion is **false**. ### Step 3: Understand the Reason The reason states that the output voltage and the input voltage of the diode have a `180°` phase difference. A `180°` phase difference means that when the input is at its maximum, the output is at its minimum, and vice versa. ### Step 4: Evaluate the Reason Diodes are unidirectional devices, meaning they allow current to flow in only one direction. This characteristic prevents them from producing a `180°` phase difference between input and output voltages. Therefore, the reason is also **false**. ### Step 5: Conclusion Since both the assertion and the reason are false, we conclude that the correct answer is that both the assertion and the reason are false. ### Final Answer: Both the assertion and the reason are false. ---
