Answer:
Option C is correct
Step-by-step explanation:
Population growth is a term that is being used to portray a change in the number of individual in a population over a period of time. This growth is defined by the growth rate which can be positive in case of accelerating population growth, it can be negative in case of diminishing/declining population growth and it can be stable or constant when the population growth is zero.
Thus, option C is the correct answer.
