Solution
The correct option is C birth rate and death rate Birth rate is the ratio of the number of individuals born in a population in a given period of time to the initial total population. The death rate is the ratio of the number of individuals who died in a population in a given period of time to the initial total population. Thus the actual rate of growth of a population is the difference between the birth rate and death rate.
