Choose the word which is different from the rest.

The answer is C. Society.

A house is a building for human habitation, especially one that is lived in by a family or small group of people. An apartment is a self-contained unit of living space within a larger building, typically with several other apartments. A building is a structure with a roof and walls, typically having several floors and supporting one or more rooms. A society is a group of people who live together in a community and share the same culture and way of life.

The word “society” is different from the rest because it is not a physical structure. The other words are all physical structures that can be inhabited by people.
