As per the given scenario, the conclusion is that the carrying capacity of area A is 15 individuals. The correct option is D.
What is carrying capacity?
The carrying capacity of an environment is the peak of population size of a biological species that can be supported by that environment, given the available food, habitat, water, and other resources.
The graph clearly shows that species populations are increasing in both areas, but the rate of population growth in area A is much faster than the rate of population growth in area B.
However, there are some constraints in both Areas A and B because their populations are not growing at an exponential rate.
Thus, the correct option is D.
