Correct answer:
C - Todos los días tengo que ordenar mi cuarto.
This is the more logical reply because it talks about something that is mentioned in the question, that is, cuarto that means bedroom. So Luisa says that she has to order his bedroom everyday. Finally, we can write this dialogue as follows:
Emily: ¿Cuántos días en la semana ordenas tu cuarto?
Luisa: Todos los días tengo que ordenar mi cuarto.
