Question

Given below are two statements : \Statement I: Elements ' $X$ ' and ' $Y$ ' are the most and least electronegative elements, respectively among $\mathrm{N}, \mathrm{As}, \mathrm{Sb}$ and P . The nature of the oxides $\mathrm{X}_2 \mathrm{O}_3$ and $\mathrm{Y}_2 \mathrm{O}_3$ is acidic and amphoteric, respectively.
 Statement II : $\quad \mathrm{BCl}_3$ is covalent in nature and gets hydrolysed in water. It produces $\left[\mathrm{B}(\mathrm{OH})_4ight]^{-}$ and $\left[\mathrm{B}\left(\mathrm{H}_2 \mathrm{O}ight)_6ight]^{3+}$ in aqueous medium.\ In the light of the above statements, choose the correct answer from the options given below :
