Bouveault-Blanc reduction reaction involves:

• A

  Reduction of an acyl halide with ${\mathrm{H}}_2/\mathrm{P}\mathrm{d}.$
• B

  Reduction of an anhydride with $\mathrm{L}\mathrm{i}\mathrm{A}\mathrm{l}{\mathrm{H}}_4$
• Correct answer
  C

  Reduction of an ester with $\mathrm{N}\mathrm{a}/{\mathrm{C}}_2{\mathrm{H}}_5\mathrm{O}\mathrm{H}$ .
• D

  Reduction of a carbonyl compound with $\mathrm{Na}/\mathrm{Hg}$ and $\mathrm{HCl}$.

Hence, the correct answer is option: 'C'.
