Q.
Output $Y$ is given by
A) $\left( \overline{X} \bullet \overline{Y} \right) \bullet Z$
B) $(X + Y)\ Z$
C) $(X + Y)\ \overline{Z}$
D) $\overline{X} \bullet \overline{Y} + \overline{Z}$
Explanation
(a) We can realize the combination as shown below.

Gate-1 is OR gate while gate-2 is AND gate.
Output of OR gate, $W_{1} = \overline{X} + \overline{Y}$
Thus, output of AND gate,
$W = W_{1} \bullet Z = (\overline{X} + \overline{Y}) \bullet Z$
