Addition of excess aqueous ammonia to a pink coloured aqueous solution of MCl_(2).6H_(2)O (X) and NH_(4)Cl gives an octahedral complex Y in the pressure of air. In aqueous solution, complex Y behaves as 1 : 3 electrolyte. The reaction of X with excess HCl at room temperature results in the formation of a blue coloured compelx Z. The calculated spin only magnetic moment of X and Z is 3.87 B.M., whereas it is zero for complex Y. Among the following options, which statement(s) is(are) correct ?
