The correct option is E 12
Carrying capacity is the maximum size of population of a species that a certain environment can support for an extended period of time. Once population overshoot the carrying capacity, it starts either decreasing as at this point, the different environmental resistances start operating or remain constant but there is not increase in population size after it. In given graph, 12 represents the point with maximum population size after which there is no increase in population size. Correct answer is E.
