E)  if the data in both statement I and II together are necessary to answer the question.

Correct Answer: E

Solution :

From I. There are two possibilities: (i) (ii) Thus, either Q or R sits in the middle of the row. Hence I alone is not sufficient to answer the question. From II. There is more than one possibility. Thus, II alone is not sufficient to answer the question. From I and II. Hence R sits exactly in the middle of the line. Thus, both are necessary to answer the question.
