Pavlov's experiment was a typical case of classical conditioning because an instinctive behavior was tied to a different stimulus an instinctive behavior was stopped due to lack of reinforcement a new behavior was learned due to positive reinforcement

I'd like to clarify the choices presented above:

-An instinctive behavior was tied to a different stimulus
-An instinctive behavior was stopped due to lack of reinforcement
-A new behavior was learned due to positive reinforcement

In the aforementioned, the answer would be 'an instinctive behavior was tied to a different stimulus'.
