Show answer & explanation

Correct answer: A

The "New-order" traversal follows the rule: Visit Right Subtree -> Visit Left Subtree -> Visit Node.

1. Start at Root A.

2. Traverse Right Subtree (Rooted at E):

- Visit Right Child I: Its right child is J, and J's right child is K. Traversing this branch yields: K, J, I.

- Visit Left Child F: It has Right child H and Left child G. Traversing yields: H, G, F.

- Visit E. Subtree Result: K, J, I, H, G, F, E.

3. Traverse Left Subtree (Rooted at B):

- Visit Right Child C: It has Left child D. Traversing yields: D, C.

- Visit B. Subtree Result: D, C, B.

4. Visit Root A.

Final Sequence: K, J, I, H, G, F, E, D, C, B, A.
