Given below are two statements:
Statement-I: The number of pairs among \( [\mathrm{Ti}^{4+}, \mathrm{V}^{2+}] \), \( [\mathrm{V}^{2+}, \mathrm{Mn}^{2+}] \), \( [\mathrm{Mn}^{2+}, \mathrm{Fe}^{3+}] \) and \( [\mathrm{V}^{2+}, \mathrm{Cr}^{2+}] \) in which both ions are coloured is \( 3 \).
Statement-II: The number of pairs among \( [\mathrm{La}^{3+}, \mathrm{Yb}^{2+}] \), \( [\mathrm{Lu}^{3+}, \mathrm{Ce}^{4+}] \) and \( [\mathrm{Ac}^{3+}, \mathrm{Lr}^{3+}] \) ions in which both are diamagnetic is \( 3 \).
In the light of the above statements, choose the correct answer from the options given below:
