1. Identify the possible complexes of $Ni^{2+}$ with the given ligands

   Nickel(II) has electronic configuration: $Ni^{2+} : [Ar]3d^8$

   The geometry depends on the ligand strength and coordination number.

2. With $Cl^-$

   Chloride is a weak-field ligand. Nickel(II) with excess chloride commonly forms: $[NiCl_4]^{2-}$ This is a $4$-coordinate complex of a weak-field ligand, so it is generally tetrahedral.

3. With $CN^-$

   Cyanide is a strong-field ligand. Nickel(II) with cyanide forms: $[Ni(CN)_4]^{2-}$ For $d^8$ nickel(II) with a strong-field ligand, the complex is square planar.

4. With $H_2O$

   Water commonly forms the hexaaqua complex: $[Ni(H_2O)_6]^{2+}$ This is a $6$-coordinate complex, which is octahedral.

5. Arrange the geometries in the required order

   For $Cl^-$, $CN^-$ and $H_2O$ respectively: $\text{tetrahedral, square planar, octahedral}$

6. Match with the options

   This corresponds to Option B.

Therefore, the correct answer is B.
