For the logic circuit shown, the truth table is:

For the logic circuit shown, the truth table is:

Options

A $\begin{cases}A & B & Y \\ 0 & 0 & 0 \\ 0 & 1 & 1 \\ 1 & 0 & 1 \\ 1 & 1 & 1\end{cases}$
B $\begin{cases}A & B & Y \\ 0 & 0 & 1 \\ 0 & 1 & 1 \\ 1 & 0 & 1 \\ 1 & 1 & 0\end{cases}$
C $\begin{cases}A & B & Y \\ 0 & 0 & 1 \\ 0 & 1 & 0 \\ 1 & 0 & 0 \\ 1 & 1 & 0\end{cases}$
D $\begin{cases}A & B & Y \\ 0 & 0 & 0 \\ 0 & 1 & 0 \\ 1 & 0 & 0 \\ 1 & 1 & 1\end{cases}$

Correct answer

D. $\begin{cases}A & B & Y \\ 0 & 0 & 0 \\ 0 & 1 & 0 \\ 1 & 0 & 0 \\ 1 & 1 & 1\end{cases}$

Step-by-step solution

$Y = \overset{¯}{\overset{¯}{A} + \overset{¯}{B}} = \overset{¯}{\overset{¯}{A}} . \overset{¯}{\overset{¯}{B}} = A . B = AND$

$\begin{cases}A & B & Y \\ 0 & 0 & 0 \\ 0 & 1 & 0 \\ 1 & 0 & 0 \\ 1 & 1 & 1\end{cases}$
