What are the correct characteristics of an RB Balanced BST? I. Keeps the time efficiency of tree operations O(log n) instead of O(h) II. In order to maintain the tree balanced, it requires to pay attention to insertion and deletion operations only; it doesn't need to consider tree traversal or search operations. III. RB Tree is a special tree balancing technique that works with any type of binary tree. IV. RB Tree uses tree height to determine when the tree needs to be rotated. a)I and IV b)II and IV c)I and II d)I and III e)II and III
