Data Sufficiency — Linear seating (facing North): Who sits immediately to the right of P among P, Q, R, S, T? Statement I: R is third to the left of Q and P is second to the right of R. Statement II: Q is immediately to the left of T, who is second to the right of P. Decide which statements are sufficient to answer the question. Choose the correct sufficiency option.

Difficulty: Medium

Statement I alone is sufficient, but Statement II alone is not sufficient.
Statement II alone is sufficient, but Statement I alone is not sufficient.
Both statements I and II together are sufficient, but neither alone is sufficient.
Either statement I or statement II alone is sufficient.
Even both statements I and II together are not sufficient.

Correct Answer: Either statement I or statement II alone is sufficient.

Explanation:

Using Statement I
Place Q, then R three to its left; P is two to the right of R. In all valid placements (for 5 seats), the person immediately to the right of P is Q.

Using Statement II
T is second to the right of P; Q is immediately left of T ⇒ Q is immediately right of P.

Conclusion
Each statement alone yields the same unique neighbor: the person to P's immediate right is Q.
