In classical conditioning, the unconditioned stimulus (UCS) naturally elicits an unconditioned response (UCR). In this case, the meat powder (UCS) caused the dog to salivate (UCR). Over time, the dog learned to associate a neutral stimulus (such as a bell) with the meat powder and began to salivate (the now conditioned response, or CR) at the sound of the bell (now a conditioned stimulus, or CS). However, in the scenario given, the meat powder is the UCS and the salivation is the UCR, making B the correct choice.
