On a micro-analysis of the foundational, functional, and structural bases of the 'Trial and Error Theory' propounded by Edward Thorndike and the 'Operant Conditioning Theory' propounded by B.F. Skinner in the psychology of learning, which of the following statements is most authentic regarding the fundamental differences between these two theories?

In Thorndike's Trial and Error theory, the Stimulus occurs first and upon getting satisfying results after the Response, the S-R bond is strengthened, which is called Thorndike's Law of Effect. In contrast, in Skinner's operant conditioning, the organism responds freely of its own accord and subsequently receives a stimulus or reinforcement, hence it is also called R-S type conditioning.
