Use the Graph to Answer the Following Question

Use the graph to answer the following question.

In the figure, curves A-D depict per capita rate increases (r) . Which of the following best explains the difference between the shapes of these curves?

A) The population growth is logistic as generations continue to form.
B) The growth is exponential for curves A and B, but because population growth for C and D is slower, it is considered logistic.
C) Population growth within each curve gets steeper as time passes because growth depends on both per capita rates of increase and current population size.
D) Curve A has the fastest rate of logistic growth.
