The demographic transition is characterized by changes in mortality rates, average life expectancy, and leading causes of death.

Answer: Option C

Explanation:

The demographic transition is a model that speaks about changes in the population of a country. It states that population of a country will eventually stop growing when the country transits from high birth rates and high death rates to low birth rate and low death rates which results in the stabilization of the population of that country. Thus it speaks about the birth rate and the death rate of the population.
