In the combination of the following gates, the output \(Y\) can be written in terms of inputs \(A\) and \(B\) as:

The given electrical network is equivalent to:
   

To get output 1 for the following circuit, the correct choice for the input is

(1) $A=1, B=0, C=0$       

(2) $A=1, B=1, C=0$

(3) $A=1, B=0, C=1$       

(4) $A=0, B=1, C=0$

What is the output \(Y\) in the following circuit, when all the three inputs \(A\), \(B\), and \(C\) are first \(0\) and then \(1\)? 
                          

To get output \(Y=1\) for the following circuit, the correct choice for the input is:
