Solution

T and Z are in the same set like 2 then according to the given restriction there is only U which cannot be in same set as T so the first answer you have selected is wrong its U 1) U 2) V is in set 2 ( because V cannot be put in set 1 with Z,W,T/U,X) here Z,W,X should be fixed according to the given restriction. If you put X in set 2 then Z should also be in set 2 so the permanent member of set one according to question 2 is Set 1 ( Z,W,T/U,X) set 2 : ( U,Y,T/U) Question 3) If X is in set 2 then Z must also be in set 2. furthermore, there will be T/U in the set 2. and no more members because set 2 only contains 3 members. Example, set 1 : T/U, V,W,Y set 2 : X,Z,T/U A) condition 1: Y is in the same set as Z, which cannot be true b) T is in set 2, yes but T can be in set 1, so it is not the condition that must be true. c) U is in set 2, yes again U can be in set 1 so it again doesnt meet the "must be true condition" d) w is in set 1, yes this is correct, because if we put w in set 2 then we have to put T and U together which breaks the rule. mostly importantly there should be only 3 members in set 2. so W should be in set 1 along with T or U, V, Y. correct answer is D) W is in set 1
