The correct answer is: $\mathrm{Zn}-\mathrm{Hg}$ conc. $\mathrm{HCl}$
In Clemmensen's reduction
$\mathrm{Zn}-\mathrm{Hg} /$ conc. $\mathrm{HCl}$ is used.
$>\mathrm{C}=\mathrm{O}+4 \mathrm{H} \stackrel{\mathrm{Zn}-\mathrm{Hg}+\text { conc. } \mathrm{HCl}}{\longrightarrow} \mathrm{CH}_{2}+\mathrm{H}_{2} \mathrm{O}$
This method is used to convert carbonyl compound into alkane.
