The correct answer is 3) dogs would salivate to the sound of a bell due to a learned response called conditioning.
To study behavior, Ivan Pavlov used dogs for a study that proved to be extremely important. In this experiment, Pavlov would ring a bell and then immediately reward dogs with food. He did this several times in order to reinforce the idea that every time the bell rang, the dog would receive food.

Ultimately, Pavlov learned that ringing this best would cause dogs to salivate, even if no food was present immediately afterwards.
