Question

To get an output of 1. from the circuit shown in figure the input must be

$a = 0, b = 1, c = 0$
$a = 1, b = 0, c = 0$
$a = 1, b = 0, c = 1$
$a = 0, b = 0, c = 1$

A

a = 0, b = 1, c = 0

B

a = 0, b = 0, c = 1

C

a = 1, b = 0, c = 1

D

a = 1, b = 0, c = 0

Solution

Verified by Toppr

To get final output as 1, the output of OR gate must be 1 and C must be 1.
So, a = 1, b =0 or a=0, b=1.
