Why the below pseudo code where x is a value, wt is weight factor and t is root node can’t insert? WeightBalanceTreeNode insert(int x, int wt, WeightBalanceTreeNode k) :   if (k == null) k = new WeightBalanceTreeNode(x, wt, null, null) else if (x < t.element) :   k.left = insert (x, wt, k.left) if (k.left.weight < k.weight) k = rotateWithRightChild (k)   else if (x > t.element) :   k.right = insert (x, wt, k.right) if (k.right.weight < k.weight) k = rotateWithLeftChild (k)

• A. when x>t. element Rotate-with-left-child should take place and vice versa
• B. the logic is incorrect
• C. the condition for rotating children is wrong
• D. insertion cannot be performed in weight balanced trees
