Which one of the following arrangements does not represent the correct order of the property stated against it?
A. `V^(2+) lt Cr^(2+) lt Mn^(2+) lt Fe^(2)` : paramagnetic behaviour
B. `Ni^(2+) lt Co^(2+) lt Fe^(2+) lt Mn^(2)` : ionic size
C. `Co^(3+) lt Fe^(3+) lt Cr^(3+) lt Sc^(3+)` : stability in aqueous solution
D. `Sc lt Ti lt Cr lt Mn` : number of oxidation states.
