II. Some B are D - False (There is no definite relation between B and D)

III. Some D are A - False (There is a "No" type of relation between D and A so Some type of relation is always invalid.)

IV. Some C are not D -True (As No A is D and some A are B and All B are C, Some C are not D is also true.)

Hence, Only I and IV follow.
