    A Both statements I and II together are necessary to answer the question. Correct Answer Incorrect Answer
    B Statement II alone is sufficient to answer the question, while statement I alone is not sufficient to answer the question. Correct Answer Incorrect Answer
    C Either statement I alone or statement II alone is sufficient to answer the question. Correct Answer Incorrect Answer
    D Statement I alone is sufficient to answer the question, while statement II alone is not sufficient to answer the question. Correct Answer Incorrect Answer

    Solution

    Statement:  I. B is 15 years younger than A. This statement alone is not sufficient to determine B's age because it provides a relationship between the ages of A and B, but we need the actual age of A or B to find B's age. II. C is 40 years old. This statement alone is not sufficient either because knowing C's age does not provide any information about B's age or the relationship between A and B. Now, let's combine the statements: If we know that C is 40 years old (Statement II) and we also know the relationship between the ages of A and B (Statement I), we can find B's age. However, if we only know Statement I or Statement II alone, it is not sufficient to determine B's age. Therefore, the answer is both statements together (I and II) are required to answer the question.
