    B If the data in the statement II alone is sufficient to answer the question, while the data in statement I alone is not sufficient to answer the question. Correct Answer Incorrect Answer
    C If the data either in the statement I alone or in statement II alone is sufficient to answer the question. Correct Answer Incorrect Answer
    D If the data in both the statement I and II together are not sufficient to answer the question. Correct Answer Incorrect Answer
    E If the data in both the statement I and II together are necessary to answer the question. Correct Answer Incorrect Answer

    Solution

    From I. There will be two cases: G/B        D             G/B        A             E              C             F                                 Case 1. D sits fourth to the left of M. E              _____   F              _____   _____   A             _____                   C                                             Case 2. Case 2 will get discarded as there are only seven person. Hence data in the statement I alone is sufficient to answer the question. From II. G             ____     _____   _____   E   ____                  C Case 1. E       ____            _____   _____   G Case 2. Hence data in the statement II alone is not sufficient to answer the question.
