Based on the statements below, choose the correct alternative.

I. Nodes with widely different degrees may coexist in the same scale-free network.

II. To mathematically study the properties of scale-free networks, we should use the continuum formalism.

III. The main difference between a random and a scale-free network comes in the tail of the degree distribution, representing the high-k region of p_k.

IV. The maximum degree represents the expected size of the largest hub in a network.

1. Only II is correct.
2. I, III and IV are correct.
3. I and IV are correct.
4. III and IV are correct.
5. None of the above.
