Answer: A. A spider Spinning a Web.
Explanation: That one should be it because every spider inherits that. It's in their blood. They don't need to be taught. A dog balancing a ball on its nose isn't right because you have to train them to do that. Same with the mouse going through a maze. A cheeta hunting prey isn't inherited. Their mother has to teach them or at least show them when they get older.
A is definitely the answer. It's an inheritance.
Hope this helps you out! ☺
