The Three requirements one must meet before becoming a member of the Senate are one you have to be at least 30 years old. Second, a U.S. citizen for at least nine years at the time of election to the Senate. And third, a resident of the state one is elected to represent in the Senate.
I think that the answer is C
I will answer in English. The three estates are:
1. The Church; those who prayed
2. Nobility; those who fought, for example knights
3. Peasantry; Everybody else under feudalism, for example those who produced the food which supported those who prayed and those who fought, the members of the First and Second Estates
