Which of the following descriptions best defines the term logistic growth

This quesion comes with 4 answer choices.

The right answer choice is the option "A.A type of growth that is exponential at first but slows as the amount reaches a certain maximum value".

This question refers to the models of exponential and logistic growths to explain how populations grow. 
 
In exponential growth the rate of growth per capita keeps constant and the population graph is a "J" shaped curve, which grows unlimited.

In logistic growth the rate of growth per capita becomes smaller and smaller ant then the population reaches a maximum. The graph is an  "S" - shaped curve.
