A loud buzzer is paired with a dim light as a signal for a dog to press a lever to gain access to food.The dog quickly learns to respond to the buzzer alone,but does not learn to respond vigorously to the light alone.According to the configural-cue approach,this is because of

B) the type of response required of the dog.
C) a generalization decrement from training to test trials.
D) the evolutionary configuration of appetitive responding.
