Given below are two statements:
Statement-I: Element 'X' and 'Y' are the most and least electronegative elements, respectively among N, As, Sb and P. The nature of the oxides \(X_{2}O_{3}\) and \(Y_{2}O_{3}\) is acidic and amphoteric, respectively.
Statement-II: \(BCl_{3}\) is covalent in nature and gets hydrolysed in water. It produces \([B(OH)_{4}]^{-}\) and \([B(H_{2}O)_{6}]^{3+}\) in aqueous medium.
In the light of the above statements, choose the correct answer from the options given below :

1. A Both Statement-I and Statement-II are true.
2. B Statement-I is true but Statement-II is false.
3. C Both Statement-I and Statement-II are false.
4. D Statement-I is false but Statement-II is true.
