Correct answer: B. Nobility
Explanation: The Estates-General was divided into three estates, or legally recognised social orders. The First Estate represented the clergy, the Second Estate represented the nobility, and the Third Estate included the common people. Thus, the correct choice is B, nobility. This arrangement reflected the unequal structure of French society before the Revolution, because the first two estates enjoyed important privileges while the Third Estate carried most direct taxation. Peasants, workers, and many urban people belonged broadly to the Third Estate, not the Second.
The word “Second” refers to the order of the estate, not to a separate economic group such as merchants or trade guilds. Nobles owned land, held special rights, and often occupied important military or administrative positions. Their representation in the Estates-General was therefore based on social rank and privilege. A useful memory link is: First Estate—clergy, Second Estate—nobility, Third Estate—commoners. This classification makes option B the only appropriate answer.
