The correct option is
B ![](https://byjus-answer-creation.s3.amazonaws.com/uploads/5334Chemistry_62b159118a09ec5f9ec58fd8_b.jpg_img_upload_solution_2022-07-07 11:44:33.218516.png)
The formation of compound will be summarized as follows:
- This is an electrophilic substitution reaction.
- Chlorobenzene is an ortho para (o, p) directing group.
- Chlorobenzene breaks a bond in phthalic anhydrate since becomes positive and becomes negatively charged.
- Hence on treating with , so eventually ortho-meta-para directing product is formed.
