¿Según manuela, ¿por qué Andrés no debe preocuparse si no conoce todas las partes del cuerpo? A. nunca va a necesitar saber tanto
B. es imposible aprenderlas todas
C. ya aprobó el examen
D. lo único importante es tener todas las partes en su lugar

I know that Andrés already took the physiology test and is asking his friend a question about one of the problems because he isn't sure if he answered correctly. I'm not sure exacly which one is correct, but I'm leaning towards C and B. If you listened to the listening portion of Unit 3 Test, please offer some guidance!
