    1. AData in Statement I alone is sufficient to answer the question while data in Statement II is not.
    2. BEither data in Statement I or Statement II is sufficient to answer the question.
    3. CData in statements I and II together are sufficient to answer the question.
    4. DData in Statement II alone is sufficient to answer the question while data in Statement I is not.
    Answer and explanation

    Correct answer: B

    Statement I fixes K with N two seats away and R to N's immediate left, which forces R into the seat to K's immediate right, so it is sufficient alone. Statement II independently fixes the arrangement as Q, P, K, R, N, M, again placing R to K's immediate right, so it too is sufficient alone. Since either statement alone answers the question, the answer is B.
