Which statement correctly states the limitation of density and social indicators?

Correct answer: Density tells number of people per area but not literacy or income directly

The direct answer is A: density tells the number of people per area, but it does not directly tell literacy or income. Density is a spatial or geographical measure. It is calculated from population and area, so it tells us how concentrated people are in a place. Option A is correct because literacy, income and health are separate social or economic indicators that require separate data. Option B is wrong because density does not tell the income of each person; income needs income statistics. Option C is wrong because density is not a complete list of education levels or literacy rates. Option D is wrong because density is not a health rate; health may be measured through indicators such as life expectancy or disease levels. The reasoning is that one indicator answers one kind of question, and it should not be used to claim more than it measures. A crowded area may have good services and high incomes, or poor services and low incomes. Memory cue: density describes where people are concentrated, not how well they live.
