Answer: C
Such teaching aids are used in campaigns.
An extension campaign is an intensive drive to spread one message, such as vaccination against a disease, to a large number of people in a short time. It relies on mass media and loudspeaker aids such as radio, television and megaphones, together with posters and meetings.
Random farm visits and individual contact are one-to-one methods, and group discussion is a face-to-face method with a small group; none of them depends on broadcast aids.
