It is noticed that \( \mathrm{Pb}^{2+} \) is more stable than \( \mathrm{Pb}^{4+} \) but \( \mathrm{Sn}^{2+} \) is less stable than \( \mathrm{Sn}^{4+} \). Observe the following reactions.
\( \mathrm{PbO}_2 + \mathrm{Pb} \rightarrow 2\mathrm{PbO} ; \ \Delta_r G^\circ (1) \)
\( \mathrm{SnO}_2 + \mathrm{Sn} \rightarrow 2\mathrm{SnO} ; \ \Delta_r G^\circ (2) \)
Identify the correct set from the following

Given below are two statements:
Statement I: \( \mathrm{F_2O} < \mathrm{H_2O} < \mathrm{Cl_2O} \) is the correct trends in terms of bond angle.
Statement II: \( \mathrm{SiF_4}, \mathrm{SnF_4} \) and \( \mathrm{PbF_4} \) are ionic in nature.
In the light of the above statements, choose the correct answer from the options given below:
