Correct answer

C. 2

Step-by-step solution

Among the given species,

\mathrm{Cr}^{2+}

and

\mathrm{Mn}^{3+}

have same number of unpaired electrons.

\begin{aligned} & \text{ Unpaired electrons, } n=4 \\ & \text{ Magnetic moment, } \begin{aligned} \mu & =\sqrt{n(n+2)}=\sqrt{4(4+2)} \\ & =\sqrt{24} \mathrm{BM} \end{aligned}

\end{aligned}$
