Quizplus · Accepted Answer

All quantum states forming a shell have the same principal quantum number n, which determines the energy level and size of the orbital. The other quantum numbers, such as the orbital and magnetic quantum numbers, vary within the same shell. The options B, C, D, and E all include quantum numbers that are specific to certain orbitals within the shell, but A is the only option that correctly identifies the quantum number that is the same for all orbitals in the same shell.
