Which of the following statement is true with respect to $\displaystyle \mathrm{H}_2 \mathrm{O}, \mathrm{NH}_3$ and $\displaystyle \mathrm{CH}_4$ ? A. The central atoms of all the molecules are $\displaystyle \mathrm{sp}^3$ hybridized. B. The $\displaystyle \mathrm{H}-\mathrm{O}-\mathrm{H}, \mathrm{H}-\mathrm{N}-\mathrm{H}$ and $\displaystyle \mathrm{H}-\mathrm{C}-\mathrm{H}$ angles in the above molecules are $\displaystyle 104.5^{\circ}, 107.5^{\circ}$ and $\displaystyle 109.5^{\circ}$, respectively. C. The increasing order of dipole moment is $\displaystyle \mathrm{CH}_4<\mathrm{NH}_3<\mathrm{H}_2 \mathrm{O}$. D. Both $\displaystyle \mathrm{H}_2 \mathrm{O}$ and $\displaystyle \mathrm{NH}_3$ are Lewis acids and $\displaystyle \mathrm{CH}_4$ is a Lewis base. E. A solution of $\displaystyle \mathrm{NH}_3$ in $\displaystyle \mathrm{H}_2 \mathrm{O}$ is basic. In this solution $\displaystyle \mathrm{NH}_3$ and $\displaystyle \mathrm{H}_2 \mathrm{O}$ act as Lowry-Bronsted acid and base respectively.Choose the correct answer from the options given below:
