The correct answer is:
$\mathrm{n}=5, \mathrm{l}=2, \mathrm{~m}_{\mathrm{l}}=-2,-1,+1,+2, \mathrm{~m}_{\mathrm{s}}=+1 / 2$
For any value of $\mathrm{I}, m_1$ value will be $-\mathrm{l}$ to $+\mathrm{I}$
So for $\mathrm{n}=5$ and $\mathrm{I}=2$ : $\mathrm{m}_{\mathrm{l}}=-2,-1,0,+1,+2$ and $\mathrm{m}_{\mathrm{s}}=+\frac{1}{2}$ or $-\frac{1}{2}$
Hence, the set $n=5, l=2, m_l=-2,-1,+1,+2, m_s=+\frac{1}{2}$ is incorrect
