The best choice is D. Posie's crying when she sees dogs is the conditioned response (CR) because it is a learned, automatic response to the sight of dogs. The bark and bite (unconditioned stimulus or UCS) caused the pain and fear (unconditioned response or UCR), which eventually became associated with the sight of dogs (conditioned stimulus or CS), leading to the development of a conditioned response (CR) of crying when Posie sees any dog.
