  The output of an OR gate is connected to both the inputs of a NAND gate. The combination will serve as a:      

A)            NOT gate

B)  NOR gate

C)  AND gate

D)  OR gate

Correct Answer: B

Solution :

[b] \[\left( \overline{A+B} \right)=NOR\] gate When both inputs of NAND gate are connected, it behaves as NOT gate \[OR+NOT=NOR\]
