Three of the following four letter-clusters are alike in a certain way and one is different. Pick the odd one out.

Correct option is A

Option (a): DLJM
· D → L → J → M
· The pattern involves alternating between moving forward and backward in the alphabet:
· D → L: +8 (D + 8 = L)
· L → J: -2 (L - 2 = J)
· J → M: +3 (J + 3 = M)
Option (b): FNKP
· F → N → K → P
· The pattern involves alternating between moving forward and backward in the alphabet:
· F → N: +8 (F + 8 = N)
· N → K: -3 (N - 3 = K)
· K → P: +5 (K + 5 = P)
Option (c): WEBG
· W → E → B → G
· The pattern is:
· W → E: +8 (W + 8 = E)
· E → B: -3 (E - 3 = B)
· B → G: +5 (B + 5 = G)
Option (d): AIFK
· A → I → F → K
· The pattern involves alternating between moving forward and backward in the alphabet:
· A → I: +8 (A + 8 = I)
· I → F: -3 (I - 3 = F)
· F → K: +5 (F + 5 = K)
Option a will be odd.
