Carmela is opening an ice-cream shop and is designing the logo for the storefront and all her advertising. Her hope is that when people see the logo, they will both feel good about her shop and experience a desire for ice cream. She has narrowed it down to four choices. Based on the principles of classical conditioning, the best logo for her to choose is

• A. a colorful cartoon of a cute animal eating ice cream.
• B. just her shop name in elegant, black-and-white font.
• C. her store name surrounding an image of an ice cream cone.
• D. a cartoon animal somewhat hidden behind the letters of the store name
