Question

Explanation:

Operant conditioning is a concept in psychology (a subfield of Social Science). Edward Thorndike laid early groundwork with his law of effect, and B.F. Skinner further developed operant conditioning. Watson was more associated with classical conditioning, Watson and Crick worked on DNA structure (not related to operant conditioning), and the pair of Thorndike and Skinner is most relevant to operant conditioning.

Answer:

C. Thorndike and Skinner
