Please Solve the Answer Accordingly and do not copy from others make sure you provide reasoning with your answer. I will dislike if the answer is poor

Consider the following implementation of insert helper method in a binary search tree: Which of the following statements about this insertHelper is TRUE? There is no problem with this method. This is a correct implementation. This inserthelper() does not make progress toward the base case, resulting in an infinite recursion. The condition (c0). The clauses for the conditions (current == null) and (c==0) need to be swapped. Setting current = newNode does not store the new node in the tree.
