Passage

When crystals of CuSO₄ . 4NH₃ are dissolved in water, there is hardly any evidence for the presence of Cu²⁺ ions or ammonia molecules. A new ion [Cu(NH₃)₄]²⁺ is furnished in which ammonia molecules are directly linked with the metal ion. Similarly, aqueous solution of Fe(CN)₂ .4KCNdoes not give tests of Fe²⁺ and CN^- ions but give test for new ion [Fe(CN)₆]^4- called ferrocyanide ion.

Q. The hybridisation and geometry and magnetic property of [Cu(NH₃)₄]²⁺ ion are

A
sp³, tetrahedral, diamagnetic

B
sp³, tetrahedral, paramagnetic

Similarly, aqueous solution of Fe(CN)₂ .4KCNdoes not give tests of Fe²⁺ and CN^- ions but give test for new ion [Fe(CN)₆]^4- called ferrocyanide ion.

Q. The hybridisation, geometry and magnetic property of [Fe(CN)₆]^4- are
