Which option correctly states a use of population density?

Answer and explanation

Correct answer: Understanding pressure of people per area

The direct answer is A: population density helps us understand the pressure of people per unit area. Density compares population with land area, so it helps planners estimate demand for water, housing, roads, schools, hospitals, food and other services. Step by step, find how many people live in a given area; compare that number with available land and facilities; a higher value generally means greater human pressure and a greater need for careful planning. Option A is correct. Option B is wrong because density cannot tell the taste of a river. Option C is wrong because it does not decide a mountain’s colour. Option D is wrong because it does not measure the height of the sky. Density may not describe every resource detail, but it is useful for settlement and resource planning. Memory cue: density connects people, land and planning.
