Which of the following is a type of call listed among the six types?

• A. Collective
• B. Announcement
• C. Query
• D. Notification

Answer: (A)

In radio nets, calls are categorized by who you’re addressing. A collective call is used to reach all stations in a net or a defined group at once, inviting anyone listening to respond. That fits the idea of a call type listed among six, because this kind of call is specifically about addressing multiple stations simultaneously rather than targeting just one. The other terms describe the content or purpose of a message—an announcement conveys information to listeners, a query asks something of a specific station, and a notification informs listeners about something—but they aren’t the method of addressing multiple stations like a collective call is. So the collective call is the correct type.
