    to all who is with option a) why you are not considering the case when BST is left skewed or right skewed then its insertion time is O(N)
    why You are going with BST

      Complexity of A can be O(n) if skew tree
      Complexity of B will be O(n)
      Complexity of Heap O(log n)
      Complexity of D O(1)
      Complexity of E O(n)

          A cant be the answer…on an average insertion in binary tree takes log n time…and in worst case it will take n comparisons….Correct ans is D as in unordered list element can be inserted anywhere…even at the start of the list…so it will take constant time to insert…
