In classical conditioning, the UCS (unconditioned stimulus) is a stimulus that naturally and automatically triggers a response without any learning needed. The UCR (unconditioned response) is the unlearned response to the unconditioned stimulus. In this scenario, the unconditioned stimulus is the kiss from Jack, and the unconditioned response is the accelerated breathing from Rose. 
The CS (conditioned stimulus) is a previously neutral stimulus that, after becoming associated with the unconditioned stimulus, eventually triggers a conditioned response. In this scenario, the conditioned stimulus is the smell of Chanel No. 5, which has been paired with the kiss from Jack. 
The CR (conditioned response) is the learned response to the previously neutral stimulus. In this scenario, the conditioned response is the accelerated breathing rate from Jack in response to smelling Chanel No. 5, which has been associated with Rose and the kiss. Therefore, the best answer is D, CR.
