Correct Answer - B
We know that, +3 oxidation is common in all series. Stable of +3 O.S. depends upon high hydration energy, high lactic energy and high I.P.
`Nd^(2+)` - has configuration `4f^(4)`
`Nd^(4+)-` has configuration `4f^(2)`
Hence `+2,+4` oxidation states are unstable in Nd in aqueous solution.
