I play piano, and I honestly think that if you can consistently practice and get a good foundation, you can become a decently good player. If you have a music room or music department in your school, you can ask to borrow their piano and go their in your free time. Or, you can ask your family again or come up with the money itself. Good luck on your piano journey :)
The best and most correct answer among the choices provided by the question is B.)The branch of philosophy that deals with beauty and how it is.
Hope this helps :)
