Analyze the following statements about the SI model with homogeneous mixing:

I. In the SI model, the fraction of infected individuals tends to zero in the final regime, since all individuals eventually recover.

II. At the beginning of the epidemic, when the fraction of infected individuals is small, the growth can be approximated by exponential growth.

III. Considering the SI model with homogeneous mixing, where β=0.4 and i=0.25, the rate at which the fraction of infected individuals changes over time is 0.075.

IV. In the SI model, the fraction of infected individuals tends to 1, meaning that everyone eventually becomes infected.

Which alternative correctly identifies the true statements?

A) Statements II, III, and IV are correct. B) Statements I, II, and IV are correct. C) Statements III and IV are correct. D) Statements I and III are correct. E) None of the above.
