Which gate acts as universal gate?

Which gate acts as universal gate? Correct Answer NAND 

Concept:

A universal gate is the one with which any other Boolean function can be implemented without the need of other gates.

Explanation:

Two universal gates are NAND and NOR.

NAND:

In this gate, output of logic gate is false only when both the inputs are true. It is the complement of AND gate.

NOR gate: Output of this logic gate is true when both inputs are false.
