The value of \(l\) varies from \(0\) to \(n-l\) and the value of \(m\) varies from \(-l\) to \(+l\) through zero. \(1\) the value of \(s \mp \frac{1}{2}\) Which signifies the spin of the electron. The correct sets of quantum number are following:

\(\begin{array}{|c|c|c|c|c|}\hline & {n} & {l} & {m} & {s} \\ \hline {\text { (ii) }} & {2} & {1} & {1} & {+1 / 2} \\ \hline {\text { (iv) }} & {1} & {0} & {0} & {-1 / 2} \\ \hline \text { (v) } & {3} & {2} & {2} & {+1 / 2} \\ \hline\end{array}\)
