# The octahedral complex of a metal ion $M^{3+}$ with four monodentate ligands $L_1, L_2 , L_3$ and $L_4$ absorb wavelengths in the region of red, green, yellow and blue, respectively. The increasing order of ligand strength of the four ligands are

$\begin{array}{1 1}(A)\;L_3 < L_2 < L_4 < L_1\\(B)\;L_1 < L_2 < L_4 < L_3\\(C)\;L_4 < L_3 < L_2 < L_1\\(D)\;L_1 < L_3 < L_2 < L_4\end{array}$

The increasing order of ligand strength of the four ligands are $L_1 < L_3 < L_2 < L_4$
Hence (D) is the correct answer.
