Q.

To get output 1 for the following circuit, the correct choice for the input is         [2016, 2012, 2010]

1 A = 1, B = 1, C = 0  
2 A = 1, B = 0, C = 1  
3 A = 0, B = 1, C = 0  
4 A = 1, B = 0, C = 0  

Ans.

(2)

Output of the circuit, Y=(A+B)·C

Y = 1 if C = 1 and A = 0, B = 1 or A = 1, B = 0 or A = B = 1
