Final answer:
The Demographic Transition Model was designed to describe the population growth changes of humans as they progress from a pre-industrial to an industrial economic system, which includes a shift from high to low birth and death rates. Hence, option (c) is correct.
Step-by-step explanation:
The Demographic Transition Model was originally devised to describe the experience of c) Humans. This model is a multistage model that reflects the changes in population growth exhibited by countries as they undergo industrialization. It describes the transition from high birth and death rates to low birth and death rates associated with the development from a pre-industrial to an industrialized economic system.
The Demographic Transition Theory suggests that there is a predictable pattern in population growth as societies evolve from an unindustrialized to a post-industrial state. Initially, high birth and death rates are common, but as a country develops economically and socially, death rates begin to fall due to improvements in medical care, sanitation, and food supply. Eventually, birth rates also decline, leading to a stabilization of the population.
