Nativism is the belief that the source of wisdom, knowledge & understanding is innate, only way you gain access to this is reasoning.
I believe the choices for this question are the following:
A. Perceptual illusions can be overcome with knowledge
B. Some perceptual illusions are not the result of experience
C. People learn new information through experience
D. People are entirely driven by responses to stimuli
So the answer would be B. A Nativist would say that some perceptual illusions are not the result of experience but instead they are from innate reasoning and knowledge.
