Eight girls X, Y, Z, U, V, W, S and T are sitting around a circular table, facing towards the centre (not necessarily in the same order). X is second to the left of U. U is third to the left of V. Z is third to the right of S. S is not the immediate neighbour of V. T is third to the right of Y. Y is second to the right of S. Three out of the following four options are similar by a certain logic and form a group. Which of the following does NOT belong to that group?
