From option [1], Only three persons are shorter than Z. Two persons have height between Z and U. As many persons are shorter than U as taller than T. Two persons have height between T and S. Y is just taller than S. Case 1: When U is taller than Z. __ > U > Y > S > Z > __ > T > __ Case 2: When U is shorter than Z. T > __ > Y > S > Z > __ > __ > U Either one or seven persons are taller than U. So, data given in option [1] is not sufficient to answer the given question. From option [2], As many persons are taller than W as shorter than V. U is taller than Z, who is just taller than X. T is the second shortest person. V is shorter than T. Y is taller than S, who is taller than Z. C is taller than S. W > Y/U > U/Y > S > Z > X > T > V Either one or two persons are taller than U. So, data given in option [2] is not sufficient to answer the given question. From option [3], Y is 3 rd tallest person. V is just shorter than T, who is shorter than S. U is taller than S, who is taller than Z. As many persons are taller than U as shorter than T. Z is taller than X W > U > Y > S > Z > X > T > V Only one person is taller than U. So, data given in option [3] is sufficient to answer the given question. From option [4], Only three persons have height between U and X. No one is taller than W. Y is taller than Z. X is taller than at most 2 persons. Y is taller than T. V is shorter than T. Number of persons taller than T is one more than the number of persons shorter than Y. No fix arrangement can be formed. So, data given in option [4] is not sufficient to answer the given question.
