Which statement is true about a B-tree having order > = t with height h and n nodes, assuming that each node takes exactly 1 disk operation to read? I. Finding a node in T cannot require more than O(h) disk operation in other words, O(h) time, if only disk reads and writes are counted. II. If each node in T is augmented with an integer showing the size of that node's subtree, then n additional nodes can be inserted into T in a total of O(n X h) CPU operations.
