We will look at the difference between the letters in each cluster:
1) GDI:
o G → D: The difference is -3 (G to D).
o D → I: The difference is +5 (D to I).
2) XUZ:
o X → U: The difference is -3 (X to U).
o U → Z: The difference is +5 (U to Z).
3) LKP:
o L → K: The difference is -1 (L to K).
o K → P: The difference is +5 (K to P).
4) SPU:
o S → P: The difference is -3 (S to P).
o P → U: The difference is +5 (P to U).
Step 2: Identify the odd one out
· Clusters 1, 2, and 4 follow the pattern where the first difference is -3 and the second difference is +5.
· Cluster 3 (LKP) has a -1 difference between the first two letters (L to K), which deviates from the other clusters.
Option (c) is the correct answer.
