Concept:Each letter in the cluster is shifted forward by 2 positions in the alphabet, and the number part is increased by 180.
Explanation:First, check the pattern: AKM420 becomes CMO600. A→C (+2), K→M (+2), M→O (+2), and 420+180=600.
Similarly, XTW710 becomes ZVY890: X→Z (+2), T→V (+2), W→Y (+2), and 710+180=890.
Now apply the same rule to LCD100:
L + 2 = N, C + 2 = E, D + 2 = F, and 100 + 180 = 280.
Thus, the coded cluster is NEF280.
Answer:Option B. NEF280
