- A
- F
- C
- B
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
In post-order traversal, the root is the last element visited. Here, the last element in the traversal is B, making it the root.
Thus, the root of the tree is \( B \).
Thus, the root of the tree is \( B \).
