The key distinction between a caste system and a class system is:

C) occupational prestige

In a caste system, one's social status is determined by birth and is typically fixed, with little to no opportunity for social mobility. Occupational prestige is determined by one's caste and is not easily changed.

In a class system, social status is based on factors such as income, education, and occupation, and individuals have more opportunities for social mobility. Occupational prestige is not predetermined by birth and can change based on individual achievements and choices.

D. Endogamy
