Given below are symbols for some logic gates

I.                   II.

III.               IV.

The XOR gate and NOR gate respectively are

A)  I and II                        

B)  II and IV             

C)  III and IV                     

D)  I and IV

Correct Answer: B

Solution :

If A and B are the two inputs of the gate, then output Y is In case of XOR gate \[\operatorname{Y} = A\overline{B}+\overline{A}B\] In case of NOR gate \[Y =\,\,\overline{A+ B}\]
