Question

To get an output $1$ from the circuit shown in the figure, the input must be

• A. $A=0,B=1,C=0$
• B. $A=1,B=0,C=0$
• C. $A=1,B=0,C=1$
• D. $A=1,B=1,C=0$

Answer 1

The correct option is C $A=1,B=0,C=1$

Input	$A+B=Y$	$Y.C=Y^{\prime }$
$(0,1,0)$	$1$	$0$
$(1,0,0)$	$1$	$0$
$(1,0,1)$	$1$	$1$
$(1,1,0)$	$1$	$0$
