I. Buildings S and Q are at the two extreme ends of the row.
II. Building T is to the right of building R.

Options

A. 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. 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. if the data either in statement I alone or in statement Il alone are sufficient to answer the question
D. if the data given in both statements I and II together are not sufficient to answer the question

Answer

D

Explanation

From statements I:
S and Q `to` Extreme ends of the row.
So, the arrangement in the row is as follows:

But there is no information regarding P, R and T. So, statement I alone is not sufficient.
From statement II :
T `gt` to the right of R.
So, the arrangement in the row is as follows: R T.
But there is no information regarding P, Q and S.
So, statement II alone is not sufficient.
From I & II, we get

So, either T or R is in the middle.
Therefore, the data in both statements I and II together are not sufficient to answer the given question.
