Step 1: Understanding the Concept:
Identifying and selecting local key leaders is vital for extension work, as rural leaders act as change agents who influence community opinions and drive technology adoption.
Step 2: Detailed Explanation:
Let us analyze the methods used to locate rural leaders:
- Sociometric method (A): Involves asking community members whom they prefer to consult or follow for specific activities. The individual with the highest choices is identified as the natural leader.
- Self-observation Self-rating method (B): Involves asking individuals within the community to evaluate their own leadership traits and influence.
- Key informant rating (C): Involves asking knowledgeable, well-informed persons (key informants) in the village to identify and rate potential leaders in the community.
These three (A, B, and C) are scientifically validated sociological methods for locating leaders.
- Brainstorming (D): This is a group creativity and problem-solving technique used to generate ideas, not a method for selecting leaders.
Therefore, the correct methods are A, B, and C only.
Step 3: Final Answer:
The correct combination is A, B, and C only, corresponding to Option (D).
