Answer:
c. (CH3CH2CH2)2CuLi
Step-by-step explanation:
(CH3CH2CH2)2CuLi
This reagent is called Lithium di(n propyl)cuprate used to covert benzoyl chloride to phenyl propyl ketone. this reagent is called Gilman Reagent and The reaction occur with nucleophilic substitution of an alkyl group for the leaving group (chloride), forming one new carbon-carbon bond.
Hence the correct answer is C that is c. (CH3CH2CH2)2CuLi
