Correct option is B
The term "paradigm" was popularized by Thomas Kuhn in his book The Structure of Scientific Revolutions (1962). It refers to a shared framework of theories, methods, and assumptions that guide scientific research within a discipline.
(C) A point of view shared by a substantial number of scientists that provides a general framework for empirical research: This definition aligns with the classical understanding of a paradigm as presented by philosopher Thomas Kuhn. A paradigm provides a shared framework for conducting research and interpreting results in a scientific community.
(D) It is usually more than just one theory and corresponds more closely to what is called a school of thought: A paradigm often encompasses more than just a single theory. It includes a collection of ideas, assumptions, methods, and shared beliefs that guide the research community, much like a school of thought.
