In a given logic circuit, the output Y when all the three inputs A , B , C are first low and then high will be respectively

Step-by-step solution

The circuit output Y is given by the Boolean expression Y = A + B C . For all inputs low ( A=0 , B=0 , C=0 ): A = 1 and B C = 1 , so Y = 1 . For all inputs high ( A=1 , B=1 , C=1 ): A = 0 and B C = 0 , so Y = 0 . The ordered pair for all inputs low then high is (1, 0), corresponding to option C .
