Q. The output of a NAND gate is 0
A) If both inputs are 0
B) If one input is 0 and the other input is 1
C) If both inputs are 1
D) Either if both inputs are 1 or if one of the inputs is 1 and the other 0
Explanation
(c) If inputs are $A$ and $B$ then output for NAND gate is $Y = \overline{AB}$
$\Rightarrow$ If $A = B = 1,\ Y = \overline{1.1} = \overline{1} = 0$
