The change from Estates-General to National Assembly shows which process?

Moving from royal consultation toward popular sovereignty

The governing concept is popular sovereignty, meaning that legitimate political authority is understood to come from the nation rather than only from the king. In 1789, representatives of the Third Estate and some supporters from other orders declared themselves the National Assembly. They claimed to represent the French nation and began acting as a law-making body, not merely as advisers summoned by the monarch. This change challenged the old system of royal authority and estate privilege. Therefore, option A is correct. Options B, C, and D describe unrelated changes in economic activity, institutions, or culture; none explains the constitutional and political transformation represented by the National Assembly.
