29The postorder traversal of a binary tree is 8, 9, 6, 7, 4, 5, 2, 3,1. The inorder traversal of the same tree is 8, 6, 9, 4, 7, 2, 5, 1, 3. The height of a tree is the length of longest path from the root to any leaf. The height of the binary tree above is __________.

Note – Numerical Type question

Option : C
Explanation :

Given, post-order – 8, 9, 6, 7, 4, 5, 2, 3, 1 and in-order – 8, 6, 9, 4, 7, 2, 5, 1, 3
So the height of tree is 4.
