(C) For $n=3$,the possible values of $l$ are $0, 1$ and $2$.Thus,there is one $3s$ orbital $(n=3, l=0, m_l=0)$; there are three $3p$ orbitals $(n=3, l=1, m_l=-1, 0, +1)$; and there are five $3d$ orbitals $(n=3, l=2, m_l=-2, -1, 0, +1, +2)$.Therefore,the total number of orbitals is $1 + 3 + 5 = 9$.Alternatively,the total number of orbitals can be calculated using the formula $n^2$,which gives $3^2 = 9$.

What is the total number of orbitals associated with the principal quantum number $n=3$?
