Which of the following gives a reversible operation?

Correct answer

3

Step-by-step solution

A logic gate gives the reversible operation if we can recover input data from the output. For example, a NOT gate gives the reversible operation because we always know that the input is the reverse of the output. For the given logic gate, let the input is X . So, the output, Y = X + X ¯ = X ¯ (NOT gate)
