As we have learned

Magnetic Moments (spin only) -

\sqrt{n\left ( n+2 \right )} where n= number of unpaired electron.

- wherein

Number of unpaired e^{-} s and corresponding magnetic moments

1\rightarrow 1.7\\2\rightarrow 2.8\\3\rightarrow 3.9\\4\rightarrow 4.9\\5\rightarrow 5.9

 

 [Fe(H_2O)_6]^{2+}has four unpaired electrons, [Cr(H_2O)_6]^{3+}[Cu(H_2O)_6]^{2+}and [Zn(H_2O)_6]^{2+}have 3, 1, 0 unpaired electrons respectively.

 


Option 1)

[Cr(H_2O)_6]^{2+}

Option 2)

[Fe(H_2O)_6]^{2+}

Option 3)

[Cu(H_2O)_6]^{2+}

Option 4)

[Zn (H_2O)_6]^{2+}
