Q56 / 75 · JEE Main 2020 (08 Jan Shift 2) · Physics

In the given circuit, value of $Y$ is:

Correct answer
A
$0$
B
toggles between $0$ and $1$
C
will not execute
D
$1$

Solution

Y = \bar{\bar{A B} ∙ A}

= \overset{̿}{A B} + \bar{A}

= A B + \bar{A}

= 0 + 0

= 0

Hence, the correct answer is option: 'A'.
