Q1:

Assertion (A): XOR gate is not universal gate. Reason (R): It is not possible to realize any Boolean function using XOR gates only.

A Both A and R are correct and R is correct explanation of A

B Both A and R are correct but R is not correct explanation of A

C A is true, R is false

D A is false, R is true

ANS:A - Both A and R are correct and R is correct explanation of A

A universal gate is one which can be used to realize any Boolean function using that type of gates only. Only NOR and NAND are universal gates.
