Are all the five friends - A, B, C, D and E - who are seated around a circular table facing the centre? I. A sites to the left of B. B faces the centre. D and E are immediate neighbours of each other. C sits second to the right of E. II. D sits second to right of C. C faces the centre. Both E and A are immediate neighbours of D. B sits second to the right of A.

Correct Answer: if the data in Statements II alone are sufficient to answer the question, while the data in Statement I alone are not sufficient to answer the question.

Explanation:

Using Statement I: We cannot determine if all the fiends are facing the centre.
A is the facing outside of C is facing the centre of circle. So, all friends are not facing the centre.
