According to crystal field theory, the correct order of ligands with respect to their decreasing order of field strength is

1. A
   $\text{CO} > \text{NH}_3 > \text{H}_2\text{O} > \text{Cl}^-$
2. B
   $\text{CO} > \text{H}_2\text{O} > \text{NH}_3 > \text{Cl}^-$
3. C
   $\text{Cl}^- > \text{H}_2\text{O} > \text{NH}_3 > \text{CO}$
4. D
   $\text{Cl}^- > \text{NH}_3 > \text{H}_2\text{O} > \text{CO}$
