Donor mode of NO ligand depends on the metal. Now, consider the following complexes (in gaseous state).(A) $[\mathrm{IrCl(CO)(PPh_3)_2(NO)}]^{+}$(B) $[\mathrm{RuCl(PPh_3)_2(NO)_2}]^{+}$(C) $[\mathrm{Co(NCS)(diars)_2(NO)}]^{+}$ , where diars $\rightarrow$ $o\text{-}(\mathrm{Me_2As})2\mathrm{C_6H_4}$.(D) $[\mathrm{Cr(CN)_5(NO)}]^{3-}$The complex (es) that do NOT exhibit bent NO coordination mode is/are
