Why was the estate system in French society not only an economic classification?

Because it was also linked with legal status and birth based rights

The estate system was more than a division based on wealth or occupation. In the old French regime, membership in an estate was connected with a person’s legal position, social rank, privileges, and duties. Birth often influenced which estate a person entered and what rights or exemptions were available. The clergy and nobility had special advantages, while the Third Estate contained most of the population and carried many obligations. Thus, estates described an unequal social and legal order as well as economic differences.

Option C expresses this complete meaning. Option A is false because rich people certainly existed in the estates. Option B is false because people followed many different occupations. Option D reduces the system to farming and ignores law, birth, status, and privilege. The correct choice therefore shows why estate divisions cannot be understood merely as income categories.
