A)  AND      

B)                         NAND

C)  NOR                     

D)         OR

Correct Answer: C

Solution :

\[\text{NOR}\]gate is obtained when the output of\[\text{OR}\]gate is made as the input of NOT gate. Boolean expression for NOR gate is                 \[Y=\overline{A+B}\] Symbol of NOR gate Truth Table

\[A\]	\[B\]	\[C\]
0 1 0 1	0 0 1 1	1 0 0 0
