Step 1: Understanding the Concept:
Extension methods are classified based on the size of the target audience into individual, group, and mass contact methods, as well as the types of instructional media used.
Step 2: Detailed Explanation:
Let us match the extension methods/materials in List-I with their descriptions in List-II:
1. (A). Farm Visit: Involves direct, face-to-face contact between the extension worker and an individual farmer, making it an Individual Contact Method. Hence, (A) matches with (II).
2. (B). Television: A powerful broadcast medium used to reach a large, diverse, and geographically dispersed audience, making it a Mass Contact Method. Hence, (B) matches with (I).
3. (C). Puppet Show: Typically conducted for a localized gathering of villagers or community members, making it a Group Contact Method. Hence, (C) matches with (IV).
4. (D). Poster: A visual medium containing illustrations and brief text, classified as a Graphic aid. Hence, (D) matches with (III).
This yields the combination: (A) - (II), (B) - (I), (C) - (IV), (D) - (III).
Step 3: Final Answer
The correct matching sequence is given by option (B).
