MCQ
The logic circuit shown above is equivalent to :
  • A

  • B

  • C


Answer

Correct option: D.

d
Truth table of the given gate :

$\begin{array}{lll}\text { A } & \text { B } & \text { C } \\ 0 & 0 & 0 \\ 0 & 1 & 1 \\ 1 & 0 & 0 \\ 1 & 1 & 0\end{array}$

Truth table of option $(1)$

$\begin{array}{lll}\text { A } & \text { B } & \text { C } \\ 0 & 0 & 1 \\ 0 & 1 & 1 \\ 1 & 0 & 0 \\ 1 & 1 & 1\end{array}$

Truth table of option $(2)$

$\begin{array}{lll}\text { A } & \text { B } & \text { C } \\ 0 & 0 & 1 \\ 0 & 1 & 0 \\ 1 & 0 & 1 \\ 1 & 1 & 1\end{array}$

Truth table of option $(3)$

$\begin{array}{lll}\text { A } & \text { B } & \text { C } \\ 0 & 0 & 1 \\ 0 & 1 & 0 \\ 1 & 0 & 0 \\ 1 & 1 & 0\end{array}$

Truth table of option $(4)$

$\begin{array}{lll}\text { A } & \text { B } & \text { C } \\ 0 & 0 & 0 \\ 0 & 1 & 1 \\ 1 & 0 & 0 \\ 1 & 1 & 0\end{array}$

Since option $(1)$ has same truth table.
