Study the following information carefully and answer the question given below:

Eight persons sit in a row facing north at consecutive multiples of 7 meters. All face north. A sits 63 meters to the left of S. R sits immediately to the right of S. The distance between A and R is the same as the distance between F and R. The difference between the total distance of W and D and the total distance of D and Y is 7 meters.

Then, F moves north and walks 50 meters to reach point C, then takes a right turn and walks 98 meters to reach point K. After that, F is northwest of U. W moves south and walks 20 meters to reach point Q, then takes a left turn and walks some distance to reach south of R.

Four of the following five are alike in a certain way and hence form a group. Which of the following does not belong to that group?
