The inorder traversal of a ternary tree is given by Left > Root > Middle > Right.
But if you apply this traversal sequence on this tree, the order is SQPTWURV.
According to the answer given by various books, the answer is (A).
(A) can only be the answer if we consider 'S' to be the left child of 'Q', and 'W' to be the left child of 'U'.
