Concept:To determine who sits to the immediate left of Z, the seating positions must be uniquely fixed.Explanation:Statement I alone:V and X are immediate neighbours of Y, and V is at an extreme end.This forces Y to be next to V, but the remaining two people can take either order on the other side.Possible arrangements: $V, Y, X, \_, \_$ or $\_, \_, X, Y, V$.The position of Z is not fixed.So Statement I alone is insufficient.Statement II alone:Z sits to the immediate left of W, and W is at an extreme end.Since W cannot be at the left extreme, W is at the right extreme.So Z is fixed at position 4, but the left neighbour of Z can be V, X, or Y.So Statement II alone is insufficient.Combining both statements:From Statement II, W is at the right extreme and Z is immediately left of W.From Statement I, V is at an extreme end and is a neighbour of Y, with X also a neighbour of Y.Using the remaining positions, the only possible arrangement is:$$V, Y, X, Z, W$$Thus, X sits to the immediate left of Z.Therefore, statements I and II together are sufficient.Answer:Option C: Data in statements I and II together are sufficient to answer the question.
