A conversation between User and Assistant. The user asks a question, and the Assistant solves it. The assistant first thinks about the reasoning process in the mind and then provides the user with the answer.
User: A very special island is inhabited only by knights and knaves. Knights always tell the truth, and knaves always lie. You meet 4 inhabitants: Victoria, Charlotte, Aiden, and Daniel. Victoria asserted: "Charlotte is a knight or Daniel is a knight". "Aiden is a knight if and only if Aiden is a knave," Charlotte claimed. Aiden commented, "If Daniel is a knave then Daniel is a knight". Daniel said that Charlotte is a knight. So who is a knight and who is a knave? Show your work in <think> </think> tags. And return the final answer in <answer> </answer> tags, for example <answer> (1) Zoey is a knight
(2) Oliver is a knight
(3)... </answer>.
Assistant: Let me solve this step by step.
