What feature of society indicates that all societies occupy a definite area?

The correct answer is that the concept of territory is fundamental in understanding societal structure. Territory refers to the specific geographic area that a society occupies, defining the physical limits within which social interactions, culture, and governance occur. This feature is essential because it sets the boundaries for social organization, resource use, and community development. Each society establishes its identity and culture within its territorial limits, making territory a crucial aspect of social cohesion and identity.

The other choices, while relevant in different contexts, do not specifically encapsulate the idea of a defined area that all societies occupy. Size relates to the population or the extent of the area, but it does not inherently signify the borders or the concept of ownership of space. Aliqueness emphasizes uniqueness within cultures but does not pertain to the geographic aspect. Demography focuses on statistical studies of populations rather than the physical space occupied by a society. Thus, territory effectively represents the connection between society and physical space, highlighting the importance of geographical boundaries in social existence.
