MCQ
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 $1$
  • If both inputs are $1$
  • D
    Either if both inputs are $1$ or if one of the inputs is $1$ and the other $0$

Answer

Correct option: C.
If both inputs are $1$
c
(c)If inputs are $A$  and $B$  then output for $NAND$ gate is $Y = \overline {AB} $
==> If $A = B = 1$, $Y = \overline {1.1} = \bar 1 = 0$
