The major product of the given reaction is?

The major product of the reaction is given by the option (B). In the first step, acid chloride is more reactive than alkyl halide. Hence, -COCl group will react first. In the second step, Friedel Craft's alkylation occurs in a position that is ortho to alkoxy group and para to methoxy group. Both methoxy and alkoxy groups are ortho para directing groups.
