The correct order of the steps in Pavlov's research on classical conditioning was:
a) presenting the bell to produce saliva; repeatedly presenting the sound of the bell followed by food; identifying the bell as a neutral stimulus; identifying food as the unconditioned stimulus.
b) identifying the bell as a neutral stimulus; repeatedly presenting the sound of the bell followed by food; presenting the bell to produce saliva; identifying food as the unconditioned stimulus.
c) identifying the bell as a neutral stimulus; identifying food as the unconditioned stimulus; repeatedly presenting the sound of the bell followed by food; presenting the sound of the bell to produce saliva.
d) presenting the bell to produce saliva; identifying the bell as a neutral stimulus; repeatedly presenting the sound of the bell followed by food; identifying food as the unconditioned stimulus.

c) identifying the bell as a neutral stimulus; identifying food as the unconditioned stimulus; repeatedly presenting the sound of the bell followed by food; presenting the sound of the bell to produce saliva.

Explanation:

Russian physiologist Ivan Pavlov was studying salivation in dogs during the 1890s and comes up with the theory of classical conditioning in which a neutral stimulus was closely associated with the unconditioned stimulus to obtain a particular conditioned response.  the theory involves learning to combine an unconditional stimulus that has already given rise to a specific response with a new stimulus so that the new stimulus results in the same response.
