Correct answer: C
Correct order of steps for Inorder Traversal:
Start traversing by visiting the nodes in the rooted tree (initialize traversal at the root).
Visit the Left subtree.
Visit the Root node.
Visit the Right subtree.
Repeat the above three steps for each subtree (this indicates the recursive application of left → root → right).
Why this order works:
Starting at the root ensures we have an entry point into the tree.
Visiting the left subtree before the root yields nodes in the left part of the tree first.
Visiting the root between left and right produces the inorder (sorted for BST) sequence.
Repeating the three-step pattern indicates recursion: apply the same left → root → right process to each subtree.
