A - Anne, Princess Royal
B - Prince Louis of Cambridge
C - Prince George of Cambridge
D - Princess Charlotte of Cambridge
Answer: D - Princess Charlotte of Cambridge
The 1701 Act of Settlement ruled that British Parliament determines the line of succession to the throne. Those in the line of succession must be Protestant and serve as head of both the Church of England and the Church of Scotland. Recent changes to the Act mean that those who marry Roman Catholics are no longer excluded (although they must remain Protestant). Furthermore, the system of male primogeniture was abandoned for any Royals born after October 28, 2011. This means that Princess Charlotte, the daughter and second child of Prince William, Duke of Cambridge, is fourth in line to the throne, after her older brother George and ahead of her younger brother, Louis.
