- 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
- C. if the data either in Statement I and or in Statement II alone is sufficient to answer the question
- D. if the data in both the Statement I and II together are necessary to answer the question Discuss
