I think you are alone in choosing option 2.narayana murthyi think 2nd option is answer
See #-Link-Snipped-# -
vikeshrajandefinitely 2 nd option is correct..............
because of these(OR and NOT)we will develop other gate i.e.NOR -
everett.pattisonThe NAND gate (inverted AND gate) is considering the universal gate because you can create any of the other logic circuits (OR, NOR, NOT, etc.) from it.

I agree that you can make a NOR gate out of OR and NOT.vikeshrajandefinitely 2 nd option is correct..............

Trouble is that the original post was this:
Which of the following can behave as a universal gate:
Option 2 does not mention a NOT gate.
1) Xnor + invertor
2)And + or
Definitely 2nd option is wrong.
Neither option can be used for a universal gate.
