According to the IUPAC naming rules, we first need to number the parent chain (benzene) in such a way that the substituents (chloro, ethyl, and propyl) get the lowest possible numbering. Here, if we number the benzene ring starting from the chlorine substituent, we get 4-chloro. Ethyl and propyl are on positions 1 and 2, respectively. Hence, the correct name is 4-chloro-1-ethyl-2-propylbenzene.
