Your answer: —  Â·  Correct: C
Explanation

The number of people per unit area of arable land is termed as physiological density. This measure provides a more accurate understanding of the population pressure on resources by relating the total population to the net cultivated or arable land [1]. In contrast, arithmetic density is a crude measure calculated by dividing the total population by the total land area [3]. Agricultural density specifically refers to the ratio of the agricultural population (farmers and their families) to the net cultivable area, rather than the total population [2]. Physiological density is often considered a superior measure for assessing food security and sustainability because it highlights the relationship between a country's population and its actual agricultural capacity to support that population.
