(C) In the given circuit,the switches $A$ and $B$ are connected in parallel with the ground. When a switch is at position $0$,it is open,and when it is at position $1$,it is closed (connected to ground).$1$. If both $A=0$ and $B=0$,both switches are open. The current flows through the $LED$ $(Y)$,so $Y=1$.$2$. If $A=0$ and $B=1$,switch $B$ is closed (grounded). The current flows through the $LED$ $(Y)$,so $Y=1$.$3$. If $A=1$ and $B=0$,switch $A$ is closed (grounded). The current flows through the $LED$ $(Y)$,so $Y=1$.$4$. If $A=1$ and $B=1$,both switches are closed (grounded). The current bypasses the $LED$ through the switches to the ground,so $Y=0$.The truth table is:$A$$B$$Y$$0$$0$$1$$0$$1$$1$$1$$0$$1$$1$$1$$0$This truth table corresponds to the $NAND$ gate operation.
