Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Rural sociology and innovation adoption theory: Everett Rogers defines diffusion as the process by which an innovation is communicated through certain channels over time among the members of a social system.
Key Formula or Approach:
\[ \text{Rogers' Diffusion Paradigm: Innovation } \xrightarrow{\text{Communication Channels}} \text{Time} \xrightarrow{\text{Social System}} \mathbf{Diffusion} \]

Step 2: Detailed Explanation:
In sociology and agricultural extension theory (Everett M. Rogers, Diffusion of Innovations):
1. Diffusion (B): Formally defined as 'the process by which an innovation (a new idea, practice, or technology) is communicated through certain channels over time among the members of a social system'.

3. Innovation: An idea, practice, or object perceived as new by an individual.
4. Communication: The exchange of information between two or more parties.

Step 3: Final Answer:
