The correct option(s) regarding the complex Coen NH33H2O3+(en = H2NCH2CH2NH2 ) is (are)

A) [Co(en)(NH3)3(H2O)]+3 complex is type of [M(AA)b3c] have two Geometrical isomers.B) If (en) is replaced by two cyanide ligand, complex will be type of [Ma3b2c] and have 3 G.I.C) [Co(en)(NH3)3(H2O)]3+ have d6 configuration (t 62g) on central metal with SFL therefore it is diamagnetic in nature.D) Complex [Co(en)(NH3)3(H2O)]3+ have lesser CFSE ( O) value than [Co(en)(NH3)4]3+ therefore complex [Co(en)(NH3)3(H2O)]+ absorbs longer wavelength for d–d transition.
