Answer:
c) two stimuli; a response and a consequence
Explanation:
In classical conditioning a person or animal is trained to associate two stimuli, while in operant conditioning a person or animal is trained to pair a response and a consequence. Classical conditioning involves two stimuli, a conditioned stimulus and a neutral stimulus. Classical conditioning is a learning process whereby a conditioned stimulus (e.g. food) is associated with a previously neutral stimulus (bell). For example, you can associate ringing a bell with feeding time in a dog through classical conditioning.
In operant conditioning, a response is paired with a consequence, for example, Dan wanted to train his dog, Rocket, to come to him when called. Every time Dan called Rocket and he came, Dan would give him a treat and pet him. Soon Rocket would come every time he was called. In this example, the response of the dog is pair with a consequence (a treat and petting).
