Answering this question really requires you to understand which Estate represents which social grouping, as once you know this information, the correct answer should be fairly obvious. The First Estate was the clergy and other religious leaders who probably accounted for no more than one percent of the population; the Second Estate was the nobility, who could not have ever been more than five percent of the population; and the Third Estate was essentially everyone else (peasants, bourgeoise, urban workers, etc.), so the Third Estate was by far the largest of three groups. The Fourth Estate is a term sometimes used to describe the media; the Fifth Estate does not exist.
