The correct answer would be option B, Gender. The primary division between people is the Gender.

Explanation:

Primary division means the main and basic thing or trait or quality or attribute on the basis of which people are divided. So the very basic and primary division between people is the gender. People are categorized primarily on the basis of their gender, i-e either they are males or females. This gender category can be further categorized as boys, girls, young male adults, young female adults, male adults, female adults, older male adults, older female adults, etc. But division on the basis of property, prestige or power are not the primary attributes, they could be secondary attributes but the primary attribute of division would definitely be the Gender.
