You have to decide whether the data provided in the statements are sufficient to answer the question. Read both the statements and give answer – 
    A If the data in statement I alone is sufficient to answer the question, while the data in statement II alone is not sufficient to answer the question. Correct Answer Incorrect Answer
    B If the data in 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 statement I alone or in statement II alone is sufficient to answer the question. Correct Answer Incorrect Answer
    D If the data in both statements I and II together are necessary to answer the question. Correct Answer Incorrect Answer
    E If the data in both statements I and II together not sufficient to answer the question. Correct Answer Incorrect Answer

    From I, We don’t know the gender of G. So statement I alone is not sufficient to answer. From II, G is the grandfather of U. So statement II alone is sufficient to answer.
