The correct option is A
The Schotten Baumann reaction can also refer to the benzoylation of active hydrogen-containing compounds with the help of benzyl chloride and aqueous sodium hydroxide. Pyridine can also be used as an alternative to the sodium hydroxide base.
The reaction is as follows:
Here, R = Ph and R' = CH3
So, product formed will be PhNHCOCH3
This is commonly known as acetanilide.
Hence, option (a) is correct.
General mechanism of this reaction follows 2 steps:
1) Attack of the nucleophile:
2) Removal of leaving group:
