   The octahedral complex of a metal ion ${\mathrm{M}}^{3+}$ with four monodentate ligands ${\mathrm{L}}_1,{\mathrm{L}}_2,{\mathrm{L}}_3$ and ${\mathrm{L}}_4$ absorb wavelengths in the region of red, green, yellow and blue, respectively. The increasing order of ligand strength of the four ligands is :

   1. A.${\mathrm{L}}_3<{\mathrm{L}}_2<{\mathrm{L}}_4<{\mathrm{L}}_1$
   2. B.${\mathrm{L}}_1<{\mathrm{L}}_2<{\mathrm{L}}_4<{\mathrm{L}}_3$
   3. C.${\mathrm{L}}_4<{\mathrm{L}}_3<{\mathrm{L}}_2<{\mathrm{L}}_1$
   4. D.${\mathrm{L}}_1<{\mathrm{L}}_3<{\mathrm{L}}_2<{\mathrm{L}}_4$
