The conductivity values in MnO is in the order of

The 3d transition metal oxides are insulators in nature. MnO is also a 3d transition metal oxide, so it is an insulator having a very low value of conductivity. This conductivity is in the range of ${10}^{-10 }- {10}^{-20} {\mathrm{ohm}}^{-1} {\mathrm{cm}}^{-1}$. Among the given options it is clear that three options represent the conductivity of conductors and semiconductors of higher magnitude. 

Hence the correct option is c) ${10}^{-10}-{10}^{-22}{\mathrm{ohm}}^{-1}{ \mathrm{cm}}^{-1}$.
