The correct option(s) regarding the complex CoenNH33H2O3+ :-
(en = H2NCH2CH2NH2 ) is (are)
It has two geometrical isomers
It will have three geometrical isomers if bidentate 'en' is replaced by two cyanide ligands
It is paramagnetic
It absorbs light at longer wavelength as compared to CoenNH343+
Solution:
(i) CoenNH33H2O+3 complex is type of [MAAb3c] have two G.I.

(B) If (en) is replaced by two cyanide ligand, complex will be type of [Ma3b2c] and have 3 G.I.

(iii) CoenNH33H2O3+ have d6 configuration (t62g6) on central metal with SFL therefore it is dimagnetic in nature.
(iv) Complex CoenNH33H2O3+ have lesser CFSE (O) value than CoenNH343+  therefore complex CoenNH33H2O+ absorbs longer wavelength for d-d transition
