In 1987, 18 black-footed ferrets, the last known individuals of this species, were captured and brought into a captive breeding program in Wyoming. In 1989, the total ferret population, still in captivity, was 120 animals. These 120 animals in 1989 represented:

A) N, the total population size. B) ∆N, the change in population size from 1987 to 1989. C) ∆N/∆t, the rate of change in population size. D) r, the per capita change in population size. E) r, the exponential rate of growth of the population.
