From left side the first gate is OR gate and next one is AND gate. So the out put of OR gate is \\\\(A+B\\\\) and the output of AND gate \\\\(Y=(A+B).C\\\\)We know that for AND gate the put will be 1 if both inputs are 1. So, \\\\(A+B =1 \\\\)and \\\\(C=1\\\\)In logic gate , \\\\( 1+0=1\\\\) so \\\\(A=1, B=0 , C=1 \\\\) will be the correct choice for output 1.
