Incorrect order of ionic size is `qquad` A) `[La^(3+)>Gd^(3+)>Eu^(3+)>Lu^(3+)]`, B)`[V^(2+)>V^(3+)>V^(4+)>V^(5+)]`,C)`[Tl^(+)>In^(+)>Sn^(2+)>Sb^(3+)]`, D)`[K^(+)>Sc^(+3)>V^(+5)>Mn^(+7)]`

Incorrect order of ionic size is \(La^{3+} > Gd^{3+} > Eu^{3+} > Lu^{3+}\) \(V^{2+} > V^{3+} > V^{4+} > V^{5+}\) \(Tl^{+} > In^{+} > Sn^{2+} > Sb^{3+}\) \(K^{+} > Sc^{+3} > V^{+5} > Mn^{+7}\)

The correct order of ionic radii Y^(3+) , La^(3+) , Eu^(3+) and Lu^(3+) is (AT. No : Y = 39, La = 57, Eu = 63, Lu = 71)
