Option C
MnO is a mettalic oxide with least oxidation state (+2). That is why, MnO is the most ionic one here.

P2O5 is a non- metallic oxide and so it must be more covalent than others which are metallic oxides. More over the metallic oxide with metal in higher oxidation state is more covalent so Mn2O7(Mn=+7state) is most covalent and MnO(Mn=+2state) is most ionic amongst Mn2O7

Remember this 2 points:;-
Less oxidation state in case of metal oxides implies more ionic 
Ionic nature :metal oxide >non metal oxides
