The complex \left [ \text{MnCl}_{6} \right ]^{3-} contains \mathrm{Mn^{3+}} ion in a weak ligand field. The electronic arrangement is shown below :

\mathrm{M n^{3+}:\left[Ar\right] 4s^{0} 3 d^{4}}

Thus, the complex is \text{sp}^{3} \text {d}^{2} hybridised with a paramagnetic nature.

Hence, the correct arswer is option (4)
