According to the stimulus-substitution model, with training, the CS activates the UR via excitation of US centers. In other words, the conditioned stimulus (CS) comes to elicit the unconditioned response (UR) by activating the same neural centers that are activated by the unconditioned stimulus (US). This leads to a learned association between the CS and the UR. Choice A and B are incorrect because the CS does not come to activate the UR or the CR directly. Choice D is incorrect because the CR does not activate the US.
