In the homogeneous-mixing SI model, which statement correctly describes the analytical solution for the time required to reach a fraction \(i(t) = 0.5\) of infected invividuals?

a) It depends only on the total population size and not on the infection rate \(\beta\)

b) It always occurs at the same time, regardless of the initial condition

c) It is inversely proportional to the contact density but not to \(\beta\)

d) It increases linearly with the initial number of infected individuals

e) None of the above.
