(D) The maximum number of electrons in an energy level with principal quantum number $n$ is given by the formula $2n^2$.Since each orbital can accommodate a maximum of $2$ electrons,the total number of orbitals in that energy level is calculated by dividing the total number of electrons by $2$.Therefore,the number of orbitals $= \frac{2n^2}{2} = n^2$.
