The increasing order of field strength of ligands is

  1. A \(\mathrm{NH}_3 < \mathrm{H}_2 \mathrm{O} < \mathrm{Cl}^{-} < \mathrm{CO} < \mathrm{CN}^{-}\)
  2. B \(\mathrm{Cl}^{-} < \mathrm{H}_2 \mathrm{O} < \mathrm{NH}_3 < \mathrm{CN}^{-} < \mathrm{CO}\)
  3. C \(\mathrm{Cl}^{-} < \mathrm{CO} < \mathrm{CN}^{-} < \mathrm{H}_2 \mathrm{O} < \mathrm{NH}_3\)
