The correct answer is A) they were angry at the king for requesting a new tax on land.
The members of the Third Estate formed the National Assembly because they were angry at the king for requesting a new tax on land.
We are talking about the French Revolution times when the people that belonged to the third state created the National Assembly in June 1789. The common French people that were part of the third state demanded the King of France to drastically change the economic system of the country. The King said no and that is when the people formed the National Assembly.
