Given below are two statements : Statement I: The number of pairs among $\displaystyle \left[\mathrm{SiO}_2, \mathrm{CO}_2\right],\left[\mathrm{SnO}, \mathrm{SnO}_2\right],\left[\mathrm{PbO}, \mathrm{PbO}_2\right]$ and $\displaystyle \left[\mathrm{GeO}, \mathrm{GeO}_2\right]$, which contain oxides that are both amphoteric is 2. Statement II : $\displaystyle \mathrm{BF}_3$ is an electron deficient molecule, can act as a Lewis acid, forms adduct with $\displaystyle \mathrm{NH}_3$ and has a trigonal planar geometry. In the light of the above statements, choose the correct answer from the options given below :
