Final Answer:
lungfish because they share more of the same nodes and traits.

──────────────────────────────────────

Explanation:
- Look at the tree. Find where “ray-finned fish” and “lungfish” branch off.
- They both come from the same point (node) that also includes “sharks.”
- That means lungfish and ray-finned fish are closer to each other than either is to sharks.
- Even though sharks look similar, they branched off earlier — so they’re less related.
- The more recent the shared node, the more closely related two animals are.
- So, lungfish is more closely related to ray-finned fish than to sharks.
