(a) In MnO2 and FeCl3 oxidation states of Mn and Fe are +4 and +3 respectively. 
(b) In (MnO4)-, CrO2Cl2 oxidation states of Mn and Cr are +7 and +6 respectively. 
(c) in [Fe(CN)6]3-, [CO(CN)6]3- oxidation states of Fe and Co are +3 and +3 respectively. 
(d) [NiCl4]2-, [COCl4]- oxidation states of Ni and Co are +2 and +3 respectively.
hence option 2 is correct.
