Step 1: Understanding the Concept:
An extension campaign is an intensive, organized educational effort designed to focus community attention on a specific problem and its solution over a defined period.
It is an effective method to create widespread awareness and interest within a large population.
Step 2: Detailed Explanation:
Let us evaluate each of the characteristics of a successful campaign:
- Organized around one major theme (A): A successful campaign must focus on a single, clear message (such as "vaccinate your cattle against FMD" or "save water").
Focusing on multiple themes (C) dilutes the message and reduces its impact.
- Well-organized (B): Because campaigns involve multiple media channels, meetings, and demonstrations across a wide area, they require careful planning, budgeting, and coordination.
- Creating a conducive environment (E): Campaigns are highly effective at creating widespread awareness, generating public interest, and creating social support for change.
- Usefulness for behavior change (D): While campaigns are excellent for creating awareness and interest, they are less effective on their own for driving deep, long-term behavior change.
That level of change usually requires individual or group contact methods, such as result demonstrations, personal farm visits, and hands-on training.
Therefore, the key characteristics of a good campaign are A, B, and E.
Step 3: Final Answer:
The correct option is (C).
