I gave my students this multiple choice question: Which is the best example of an inherited behavior?

Only one answer is correct among these 4 choices:
- a bear knowing the best place to catch salmon
- a cat clawing on a tree to sharpen its claws
- a dog coming when it hears a bell
- a horse trotting its way back to the barn

Could you tell me which one is correct?

a cat clawing on a tree to sharpen its claws
