$Δ E = 13.6 Z^{2} (\frac{1}{n_{1}^{2}} - \frac{1}{n_{2}^{2}})$

$\begin{matrix} Series & n_{1} & n_{2} \\ A) & Paschen (1st line) & 3 & 4 \\ B) & Balmer (2nd line) & 2 & 4 \\ C) & Paschen (3rd line) & 3 & 6 \\ D) & Brackett (4th line) & 4 & 8 \end{matrix}$

$So correct ascending order of energy of above lines is:$

$D < A < C < B$
