What is \( X \) and \( Y \) ?
\( \longrightarrow \xrightarrow[Y]{X} \)
\( X: \mathrm{Hg}(\mathrm{OAc})_{2}, \mathrm{H}_{2} \mathrm{O} \quad \mathrm{Y}: \mathrm{NaBH}_{4} \)
\( X: B_{3} \quad Y: H_{2} \mathrm{O}_{2} \)
X: \( \mathrm{H}_{2} \mathrm{SO}_{4} \mathrm{Y}: \mathrm{H}_{2} \mathrm{O} \)
All the choices are correct
