|A) If the data in statement I alone are sufficient to answer the question||B) If the data in statement II alone are sufficient answer the question|
|C) If the data either in I or II alone are sufficient to answer the question;||D) If the data in both the statements together are needed.|
Clearly, we have the order : A. a E. From I, we have the order : D, A, B. E.
From II, we get the complete sequence as D, A, B. E, C.
Clearly. B is in the middle. So, both I and II are required.
