Answer:
I believe the correct answer is D.
Step-by-step explanation:
Writing editorials would be the editor's and journalist's job. Creating graphics for advertisements could be a possible answer, but those would be created by either the advertiser themselves or a graphic designer that they hired. Maintaining a social media account is another possible option, but pretty limited seeing as we don't have enough information to know if the artist is the one creating the posts or is being given what to post by their employer. D is the best option. Hope this helped!!
