Answer: b. Whether the article will have an accompanying commentary.
Explanation;
Commentary for the publication of manuscript involves the article along with which the manuscript is published. It is not mandatory for the publication of the manuscript. The chief editor of the journal invites the well known author or professional to comment on the manuscript by creating an additional article so that it may receive more attention from the readers.
It may be either Disagreements or Intractable Situations. I'm not completely sure, sorry. I'd wait for another to come answer your question just to be safe.
