The correct statements about the Marquis de Lafayette are:
- He was a French nobleman and friend of George Washington.
- He led troops and became known as “the Hero of Two Worlds.”
- He asked the king of France to send troops to help fight the British.
The statement "He acted as a French spy to gain information for American troops" is not accurate in the context typically associated with Lafayette. While he did gather information and played a vital role in the American Revolutionary War, he is not specifically known as a spy.
