Here's why it's not possible to answer without more information:
* It's incomplete: It's like saying "That you..." in English. You need the rest of the sentence to understand the question or statement.
* It has various meanings: "Que tu" can be part of different grammatical structures:
* A relative clause: "Que tu aimes" (That you like)
* A direct object pronoun: "Que tu vois" (That you see)
* A conjunction: "Que tu le fasses ou non" (Whether you do it or not)
To answer "que tu", you need the full sentence:
* Example 1: "Que tu aimes le chocolat?" (Do you like chocolate?)
* Answer: "Oui, j'aime le chocolat." (Yes, I like chocolate.)
* Example 2: "Je sais que tu es fatigué." (I know that you are tired.)
* Answer: This is a statement, not a question, so no direct response is needed. You could acknowledge it with "Oui, c'est vrai." (Yes, that's true.)
Please provide the full sentence containing "que tu" so I can help you answer it accurately.
