Extra programmes to make the already exiting radio programmes more attractive and interesting are well known as (A) Add-ons (B) Infusions (C) go-buttons (D) Frills Correct Ans: (D) Explanation: Frills refer to additional features that enhance the appeal of existing radio programs. These elements include sound effects, jingles, background music, celebrity interactions, and listener call-ins. Broadcasters use frills to keep audiences engaged and improve the overall listening experience. For example, a simple news bulletin becomes more engaging with theme music, expert commentary, or interactive segments. Similarly, a music show gains excitement with song dedications, trivia, and contests. These elements do not change the core content but make it more appealing. The other options do not accurately describe this concept. Add-ons generally refer to additional content, not enhancements. Infusions mean mixing new elements into a program rather than improving its existing structure. Go-buttons are not a recognized term in radio broadcasting. By using frills, radio stations retain listener interest and make programs more dynamic and entertaining.
