The correct answer is B. There may not be enough workers to sustain economic growth.
Explanation
The population is a term referring to a set of organisms that live in a specific geographic space or territory. This concept is usually associated with the number of people who live in a certain place such as a country, department/state, city, town, among others. In addition, it is usually used to know the growth or decrease of the birth and mortality rates of a population that influence the social dynamics of a community. According to the above, if the country's population growth is slow, the birth rate would be low, this would affect the country's workforce because a slowly growth (few births) of the population would affect the number of people who can work, which would affect directly economic growth. Therefore, the correct answer is B. There may not be enough workers to sustain economic growth.
