Question

For the following circuit to give output as 1, the correct choice for the input is

• A. A=1, B=0, C=0
• B. A=1, B=1, C=0
• C. A=1, B=0, C=1
• D. A=0, B=1, C=0

Answer 1

The correct option is C A=1, B=0, C=1

Consider the given figure, the resultant boolean expression of the above logic circuit will be $Y=(A+B)C$
Considering all options one by one, we get output Y = 1 with inputs A = 1, B = 0, C = 1.
