Answer 4

A) It is universal and invariable.

Think of older Indian society where there were the "untouchables" at the bottom of the social hierarchy. It persisted over generations, was supported by a belief system, and was a characteristic of their society. However, that particular system of  stratification would not hold true in other cultures, so is therefore not universal.
