Best answer
Right choice is (b) N-Phenylethanamide and acetic acid

To explain: The H atom attached to nitrogen of aniline is replaced by COCH3 group of ethanoic anhydride. This forms N-phenylethanamide (or acetanilide). The by product (acetic acid) is formed by the attachment of the H atom from aniline with remaining CH3COO part of ethanoic anhydride.
