a broken branch on a pine tree a hollow in an oak tree a scar on a maple tree a thick trunk on a pecan tree
I gave my students this multiple choice question: Which is an inherited characteristic of a tree?

Only one answer is correct among these 4 choices:
- a broken branch on a pine tree
- a hollow in an oak tree
- a scar on a maple tree
- a thick trunk on a pecan tree

Could you tell me which one is correct?
