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 ... EXOR which will be implemented by EXOR.So should it be C? I am specifically talking about "ANY" keyword in Second statement.

Self Dual and Neutral Function in digital electonics
I have seen this concept in one of the test series then i referred morris mano but not able to find this concept. I looked at some online definitions (One of them is https://gateoverflow.in/1958/gate2014-2_6) and people are defining it ... two concepts?
