If a district has a very large total population but it is spread over a large area, which conclusion cannot be drawn only from population size?

Its population density is also definitely very high

Population size means the total number of people living in a place. Population density is different: it shows how many people live, on average, in each unit of area. Density depends on both population and area, usually expressed as population divided by land area. A large district can have many people but still have a moderate or low density if its territory is very large.

Option A is correct because total population alone cannot prove that density is also very high. The statement about a high number of people may follow directly from population size, while planning can use population data. Area is necessary for calculating density. The other choices recognize these distinctions, whereas A incorrectly treats size and density as the same measure.
