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

Answer: Option A
