In the patent examination opinion, "the attached mark does not appear in the attachment", how to reply can be modified within the scope?

The easiest way is to delete the reference number (such as 125) that does not appear in the drawing from the specification (such as all "elements 125" in the specification are changed to "elements"). This won't be out of range. Of course, it is best to communicate with the examiner by phone before submitting a reply, just in case.
