Given: D ≤ U
1) E ≥ D ≤ V = P < W ≤ U → False (as D ≤ V < W ≤ U → D < U).
2) T ≥ U ≥ N = F ≤ J ≥ D → False (as U ≥ N ≤ J ≥ D → hence clear relation between U & D cannot defined).
3) D ≥ C > Z ≥ B = O ≤ U → False (as D ≥ C > Z ≥ B ≤ U → hence clear relation between D & U cannot defined).
4) G ≥ D = J < B ≤ W ≤ U → False (as D < B ≤ W ≤ U → D < U).
5) U ≥ L = G ≥ X = Y ≥ D → True (as U ≥ L ≥ X ≥ D → U ≥ D).
Clearly, fifth expression is definitely true.
