I gave my students this multiple choice question: Which characteristic is an example of learned behavior?

Only one answer is correct among these 4 choices:
- a bear hibernating in the winter
- a spider spinning a web in a tree
- a butterfly migrating to the south
- a dog scratching at a door to go out

Could you tell me which one is correct?
