Explanation:
Answer:
el heroe subio a la Torre para rescatar a la princesa
I don't think the sentence would make any sense if you would have even tried to put any "tu" in the it.
The answer would be "sabes" it means "do you know" conoces mean also "do you know" but it refears if you know someone and sabes is if you know about something, "sabemos" means we know and "conosiste" means did you meet
Hope this helps
