In classical conditioning, the responses involved tend to be but in operant conditioning they are a. complex and not reflexive; reflexive b. emitted; automatic c. reflexive; complex and not reflexive d. secondary reinforcers; primary reinforcers

The answer is C.

In classical conditioning, the responses involved tend to be reflexive, but in operant conditioning, they are complex and not reflexive. Both classical and operant conditioning includes behaviors that are controlled by stimuli in the environment. However, they have a difference in terms of nature. Classical conditioning is a stimulus that produces behavior in a reflexive way, while operant conditioning is a stimulus that comes from punishment or reward.
