• A. If the data in statement I alone is sufficient to answer the question.
• B. If the data in statement II alone is sufficient to answer the question.
• C. If data in both statement I and II together are not sufficient to answer the question
• D. If the data in both statement I and II together are sufficient to answer the question.

Answer 1

Answer:

C. If data in both statement I and II together are not sufficient to answer the question

From both I and II together, we can conclude that A and B are the children of D, but the sex of A and the third child of D is not known. So, both the statements together are also not sufficient to answer the question.
