To answer this type question firstly we should know that: Charge on NH3 =0(zero)
                    Charge on H2O=0(zero)
                    Charge on CO =0 (zero) 
Please note that CO(carbonyl group) is different from the Co(Cobalt).
So now if we look at the 3rd option.
In Ni(CO)4  we will put oxidation state of CO = 0 and for Ni we will put x which we have to find. 
So now X + 4*(0) = 0
              X + 0 = 0 
             X = 0 
That means oxidation state of Ni in Ni(CO)4 is 0(zero)
