The concept of classical conditioning is based upon which of the following scientists experiments

Classical conditioning is based on Pavlov's experiments. The most famous and used example is that of a salivating dog. Pavlov would ring a bell before feeding the dog, up to the point where the dog would learn, or became conditioned, that whenever the bell would ring, it was about to be fed. Thus, every instance where Pavlov rang the bell, the dog would salivate as its brain prepared the body for feeding.
