Accepted Answer

$$\begin{aligned} & ext { Energy difference } \Delta E=\frac{h c}{\lambda} \ & herefore \lambda \propto \frac{1}{\Delta E} \ & (\Delta E)_{6-2}>(\Delta E)_{5-2}>(\Delta E)_{4-2}>(\Delta E)_{3-2} \ & \lambda_{6-2}<\lambda_{5-2}<\lambda_{4-2}<\lambda_{3-2} \end{aligned}$$ A-III, B-IV, C-II, D-I
