(D) Ethyl phenyl ketone $(C_6H_5-CO-CH_2-CH_3)$ is formed in all the given reactions.$(a)$ Nitriles react with Grignard reagents followed by hydrolysis to give ketones: $C_6H_5-CN + CH_3-CH_2-MgBr$ $\rightarrow C_6H_5-C(CH_2-CH_3)=NMgBr$ $\xrightarrow{H_3O^{+}} C_6H_5-CO-CH_2-CH_3$.$(b)$ Acid chlorides react with dialkyl/diaryl cadmium to give ketones: $2CH_3-CH_2-COCl + (C_6H_5)_2Cd \rightarrow 2C_6H_5-CO-CH_2-CH_3 + CdCl_2$.$(c)$ Benzene undergoes Friedel-Crafts acylation with propanoyl chloride to give ethyl phenyl ketone: $C_6H_6 + CH_3-CH_2-COCl \xrightarrow{AlCl_3} C_6H_5-CO-CH_2-CH_3 + HCl$.

In which of the following reactions is ethyl phenyl ketone obtained?
