230cc or 265cc? Currently an A cup and want to be a small C cup. (Motiva Ergonomix, demi profile)

Hi Doctors, I had my consultation last month and my surgeon has ordered 205cc, 230cc and 265cc weights. I’m currently an A cup (with barely any boobs) and wanting to be a small C cup. I’ve attached my 3D imaging and the stimulated picture is with 230cc. I’m wondering if that will be enough or should I go with 265cc to get a C cup? I’m 23 years old, 55kg and 158cm tall Thanks for your time, Nat :)
