Arrange the following concepts in the correct order of influence on social mobility, from most restrictive to most flexible: A) Ascribed status B) Caste system C) Achieved status D) Open stratification system

To understand the influence on social mobility, we can start with the caste system, which is the most restrictive. In a caste system, individuals are born into specific social groups that limit their opportunities for movement; they usually cannot change their status regardless of their efforts. Next is ascribed status, which refers to traits or characteristics that individuals are born with, like race or family background, that can also limit mobility but may allow for some movement in certain contexts. Achieved status comes next, as it represents the social position a person attains through their actions, like education or job performance, allowing for more flexibility. Finally, an open stratification system provides the most flexibility, as it encourages movement between different social classes based on personal achievements rather than fixed traits.
