I. R is between P and S.
II. S is to the immediate right of R.

Options

A. (1) if the data in statement I alone are sufficient to answer the question, while the data in statement II alone are not sufficient to answer the question
B. (2) if the data in statement II alone are sufficient to answer the question, while the data in statement I alone are not sufficient to answer the question
C. (3) if the data either in statement I alone or in statement Il alone are sufficient to answer the question
D. (4) if the data in both statements I and II together are necessary to answer the question.

Answer

D

Explanation

From statement I: Between P and S `to` R .

But there is no information regarding Q. So, statement I alone is not sufficient.
From statement II: S`to` Immediate right of R.

But there is no information regarding Q. So, statement II alone is not sufficient.
From I & II, we get

So, P `to` Immediate right of Q.
Therefore, the data in both statements I and II together are necessary to answer the given question.
