What is the output

Y

in the following circuit, when, all the three inputs

A, B, C

are first

0

and then,

1

?

Options

A $0, 1$
B $0, 0$
C $1, 0$
D $1, 1$

Correct answer

C. $1, 0$

Step-by-step solution

Output,

Y = \overset{¯}{\left(A ⋅ B\right) ⋅ C} = \overset{¯}{A} + \overset{¯}{B} + \overset{¯}{C}

.

When,

A, B, C

are

0 \to Y = 1

.

When,

A, B, C

are

1 \to Y = 0

.
