Bouveault-Blanc reduction reaction involves :
Reduction of an acyl halide with H2/Pd
Reduction of an ester with Na/C2H5OH
Reduction of carbonyl compound with Na/Hg and HCl
Reduction of an anhydride with LiAlH4
Bouveault Balance reduction -
Reduction of carboxyl compounds and esters to alcohols by using alcoholic sodium.
Reduction using Na in ethanol is called Bouveault - Blanc reduction.
Therefore, option 2 is correct.
