I'd say A is definitely the correct answer, but also C could be, if the Valley is a place, I really don't know if it is.
I would go with Readers' Guide, because it lists hundreds of magazines. Usually, there is a reference list for all the available magazine articles that is arranged alphabetically by subject. This is called a reader's guide. A newspaper index is a reference for newspapers base on the issue date while a card catalog is a reference in finding authors of books. So the correct answer is C. I hope this answer helped you <3
