B. The quantum number that indicates the energy level of the electron
C. A subdivision of an energy level in an atom
D. The probability of finding the electron at a radius r from the nucleus

I would go with d.
the answer was b
OK but I disagree. b can be right in certain cases, as in the case of the H atom, but for other atoms the orbitals(s,p,d,f) determine the energy of the electrons. The answer d is correct for n of any element.

Can you give me the answer key for Which of the following is described by a principal quantum number?
i am a little late but the answer is in fact B:)
