Correct answer: B

Recall the Bouveault–Blanc reduction

The Bouveault–Blanc reduction is the reduction of an ester to alcohols using sodium metal in alcohol (commonly ethanol).

General reaction:
$RCOOR' \xrightarrow[\text{alcohol}]{Na} RCH_2OH + R'OH$
Check each option

A. Reduction of an acyl halide with $H_2$ /Pd

This is catalytic hydrogenation, not Bouveault–Blanc reduction.

Incorrect.

B. Reduction of an ester with $Na/C_2H_5OH$

This exactly matches the Bouveault–Blanc reduction.

Correct.

C. Reduction of a carbonyl compound with Na/Hg and HCl

This corresponds to other reduction conditions, not Bouveault–Blanc reduction.

Incorrect.

D. Reduction of an anhydride with $LiAlH_4$

This is hydride reduction by $LiAlH_4$ , not Bouveault–Blanc reduction.

Incorrect.
Final answer

The Bouveault–Blanc reduction involves:
$\boxed{\text{Reduction of an ester with } Na/C_2H_5OH}$
