The phylogenetic tree was constructed using derived traits of organisms A, B, C, D, and E. Based on the tree, which two organisms share the most derived traits?

• C and D because they share one common branch.

• C and D because they are closest to the end of the tree next to each other.

• A and B because they share the most branch points.

• A and B because they are the pair closest to the center.
