Studies of Social Transmission of Food Preferences in Rats Have

Studies of social transmission of food preferences in rats have shown that:

A) rats are more likely to eat a novel food if they smell the food on another rat's breath after observing the other rat eating the food.
B) a novel food can become a preferred food if a rat observes another rat eating the food, even if the observer rat never smells the food.
C) food preferences that are learned through observation are not passed down to subsequent generations.
D) rats can learn to eat, but not to avoid, novel foods by observing another rat eating the food.
