The system with given pole-zero diagram is
Answer: Option
Explanation:
Because no.of zero is more than Pole, therefore when you find transfer function.
Numerator power will higher than denominator, and such transfer functions is not realizable.

One pole and one zero cancels each other i.e. 1/4. H(z) = z + 3(z/z - 4).
For if roc is |z|>4 then it is not stable and if ROC is |z|<4 then it is stable. But ROC is not mentioned in question so it is not possible to define stability.

Yes @Vikas. It must be non-causal system.

If Numerator power is higher than denominator I heard it is a non-causal system.
Can anyone give me clarity about this?
