The Correct Option is D

Step 1: Understanding the Concept:
Extension education history features several landmark conceptual frameworks, publications, and institutional definitions.
Matching prominent extension pioneers and organizations with their key contribution years helps trace the development of the discipline.

Step 2: Detailed Explanation:
