Explanation / Answer

Answer is C.

1)Because negation of x is x and negation of z is z The reason is that x means input can either be 0 or 1. So output will also be 0 or1 i.e x. Z means high impedance state. It is neither 0 nor 1. It's negation will obviously be z. So, the option is C.

2)or operation of 0 with x is x. And 0 with z is x.

3) ex or of 0 with x is x & 0 with z is x

4) ex nor of 0 with x is x and 0 with z is x
