Which option correctly relates population growth and birth rate?

Answer and explanation

Correct answer: A high birth rate can increase population growth, but death rate and migration also matter.

Correct answer: A. Population change depends on more than births. A useful basic relationship is: population change is affected by births and people entering an area, while deaths and people leaving an area reduce the total. Therefore, a high birth rate can contribute to growth, but its effect may be reduced by a high death rate or outward migration. B is wrong because birth rate is only one factor. C is wrong because more deaths reduce the number of people and can lower growth. D is wrong because the word “always” ignores mortality and migration. The phrase “can increase” is balanced: it states a possible effect without claiming that one factor explains every situation. Memory cue: births and arrivals add; deaths and departures subtract.
