d- and f-Block · Colour and magnetism of ions

Given below are two statements :

Statement I : The number of pairs among [$\ce{Ti^4+}$, $\ce{V^2+}$], [$\ce{V^2+}$, $\ce{Mn^2+}$], [$\ce{Mn^2+}$, $\ce{Fe^3+}$] and [$\ce{V^2+}$, $\ce{Cr^2+}$] in which both ions are coloured is 3.

Statement II : The number of pairs among [$\ce{La^3+}$, $\ce{Yb^2+}$], [$\ce{Lu^3+}$, $\ce{Ce^4+}$] and [$\ce{Ac^3+}$, $\ce{Lr^3+}$] ions in which both are diamagnetic is 3.

In the light of the above statements, choose the correct answer from the option given below :
