In which situation will natural increase of population be zero?

Answer and explanation

Correct answer: When the number of births equals the number of deaths.

The correct answer is A. Natural increase means the change caused only by births and deaths; migration is not included in this specific measure. The basic relationship is natural increase = number of births − number of deaths. If births and deaths are equal, their difference is zero, so the population has zero natural increase. This does not necessarily mean that the total population remains unchanged, because immigration or emigration could still alter it. A is correct because it gives the exact condition. B is wrong because migration affects total population change, not natural increase. C is wrong because a census counts people but does not itself create births or deaths. D is wrong because a larger area changes the size of the territory, not the number of people. Memory cue: natural means births and deaths only; equal numbers give zero.
