Answer 2

The correct increasing order of splitting power of ligands according to spectrochemical series is $Cl^-<OH^-<CN^-$.

• According to spectrochemical series as the ligands field strength increases the splitting of the d orbital also increases.
• Cyanide ion is a strong field ligands so, makes higher splitting.
• Hydroxyl ion is a moderately strong field ligands so, makes moderate splitting.
• Chloride ion is a weak field ligands so, makes lower splitting.
• The correct increasing order of splitting power of ligands according to spectrochemical series is $Cl^-<OH^-<CN^-$.
• Hence the correct option is a.
