Four of the following five are alike in a certain way and hence form a group. Find the one who doesn’t belong to that group.

1) At least three persons stand to the right of the one who is from 6th. Only two persons stand between the one who is from 6th and W who stands to the immediate right of U. Case-1 2) The number of persons to the right of W is the same as the number of persons to the left of T, who is from 10th. The one who stands fourth to the right of T is immediate junior to T. Hence, case 4 gets eliminated. Case-1 3) The one who is from 5th stands second to the left of the one who is from 9th. R is from 4th but doesn’t stand adjacent to W. More than four persons stand between R and V. Hence, case 1 gets eliminated. Case-2 4) Q is neither from 6th nor 7th. Neither the one who is from 7th nor the one who is from 8th stand at any of the ends. Hence, case 2 gets eliminated. Case-3
