There are many perfumes in the market, but only one that breaks down fragrances into elements so people can wear the particular scents with which they have emotional ties. The perfume's manufacturer is Demeter, and it makes over 150 different fragrances with names like Dirt, Lobster, Dandelion, Sugar Cookie, Brownie, Woodsmoke, Leather, and Turpentine. Because repeated exposure to these scents has made us connect them with some important event or memory, we can say the appeal of the scent is due to: A. cognitive learning. B. cognitive dissonance. C. behavioural learning. D. functional adaptation.
