The possible values of principal quantum number $\text{'}\mathrm{n}\text{'}$ can be any positive integer.

For a particular value of $\text{'}\mathrm{n}\text{'}$, the possible values of azimuthal quantum number is from $0$ to $\left(\mathrm{n}-1\right)$.

Thus, for $\mathrm{n}=3$, the possible $\text{'}\mathrm{l}\text{'}$ values are $0, 1, 2$.

The possible values of magnetic quantum number $\text{'}\mathrm{m}\text{'}$ is from $\text{'}-\mathrm{l}\text{'}$ to $\text{'}+\mathrm{l}\text{'}$.

Thus, for $\mathrm{l}=2$, the possible values of $\text{'}\mathrm{m}\text{'}$ are $-2, -1, 0, +1, +2$.

The possible values of spin quantum number $\text{'}\mathrm{s}\text{'}$ is $-\frac{1}{2}$ and $+\frac{1}{2}$.

In option C.

$\Rightarrow \mathrm{l}=3,$ not possible for $\mathrm{n}=3$
