Answer:
C) Ads in only one local paper may appear to be discriminatory.
Step-by-step explanation:
When placing the ads, one must be sure they don't come off as discriminatory or targeted for just a certain class of people.
If the newspaper where the ads are placed are distributed only in one area, it might be seen only by the people who are living there. This can potentially exclude certain races, classes, and other identity profiles of various people who do not live in that certain neighborhood.
This should be avoided at every cost, so it is better to put ads in the newspaper distributed through a variety of neighborhoods.
