Solution

The correct option is B Acetaldehyde

The compound (C) is acetaldehyde $C H_{3} C H O$ . In Rosenmund's reaction, acid chloride (such as acetyl chloride) reacts with hydrogen in the presence of Pd / $B a S O_{4}$ / quinoline to formaldehyde (such as acetaldehyde).

Hence, the correct option is $C$
