Answer:A conditioned taste aversion
Explanation:
A conditioned taste aversion refers to how we tend to avoid the food after we have eaten it and got Ill.
This is how classical conditioning has an impact on our behavior. This occurs even if we have only eaten that type of food once.
Let say you ate a piece of blue berry pie and afterwards you felt ill and after that everytime when you think about blueberry pie you begin to feel queasy, this si what is referred to a conditioned taste aversion.
Dimitri is experiencing the same thing because he feels ill just when they stop for donut even before he eats it, just the thought of it.
