Which of the following arrangements does not represent the correct order of the property stated against it?

Evaluation:Ionic size: Across a period, as atomic number increases, ionic size decreases. So ${\text{Mn}}^{2+}>{\text{Fe}}^{2+}>{\text{Co}}^{2+}>{\text{Ni}}^{2+}$ is correct.Stability in aqueous solution depends on hydration energy. High hydration energy leads to higher stability. ${\text{Sc}}^{3+}$ is actually the least stable among these due to having the lowest hydration enthalpy.Oxidation states: $\text{Sc}(+3)$, $\text{Ti}(+2,+3,+4)$, $\text{Cr}(+2\text{ to }+6)$, $\text{Mn}(+2\text{ to }+7)$. Order is correct.Paramagnetic behaviour depends on unpaired electrons: ${\text{V}}^{2+}(3)$, ${\text{Cr}}^{2+}(4)$, ${\text{Mn}}^{2+}(5)$, ${\text{Fe}}^{2+}(4)$. The order ${\text{Mn}}^{2+}<{\text{Fe}}^{2+}$ is incorrect.
