Fertility refers to the number of births within a population, mortality refers to the number of deaths within a population, and net migration takes into account both immigration (people moving into a population) and emigration (people moving out of a population), which directly affects the size of a population. Therefore, A is the correct choice. B and C are incorrect as they do not include net migration, and D is incorrect as it does not include immigration.
