The capacity of individuals or groups to transition across social strata is known as social mobility. This transition can be upward (advancement to a superior social class) or downward (descent to an inferior social class) and may be influenced by factors like education, employment, and economic shifts.
Social integration (B) describes the assimilation of individuals into society, social cohesion (C) denotes the solidarity and connections that bind a society, and social deviance (D) encompasses actions that contravene societal standards. Consequently, social mobility accurately describes class movement.
