Solution

The correct option is D V
The first half of curve (I to III) represents the exponential growth of population while the fluctuating part (IV) represents logistic growth of the population. The solid line represents carrying capacity (V) which is the maximum size of the population of a species that a certain environment can support for an extended period of time. Once population overshoots the carrying capacity, it starts decreasing as at this point. Thus, the correct answer is E.
