Solution
The correct option is C Gate 3 is a universal gate.
Universal gate is a gate by which every other gate can be realized.
Gate 1 and Gate 2 are basic gates and can not be used as universal gates.
Gate 3 is universal gate.
this is because,
if we ground Y, it gives output ¯X.
Now, by connecting this output at the terminal of this gate, we will get X+Y.
Similarly, X.Y can also be obtained.
