Which option gives the correct conditional relation between population growth and population density?

Answer and explanation

Correct answer: Density may rise if population increases and area remains same

Direct answer: A. Population density means the number of people per unit of area, commonly written as population ÷ area. If the population increases while the area stays constant, the numerator rises and density may rise. A is correct because it states the necessary condition rather than claiming that growth always changes density in the same way. B is wrong: population growth does not automatically enlarge the geographical area. C is wrong because density depends on both population and area; death rate can influence population but does not alone determine density. D is wrong because growth measures change over time, whereas density describes population concentration at a place and time. If area also expands, density might stay unchanged or even fall, so the condition in A matters. Memory cue: density is people per area; growth is change in people over time.
