Based on the English alphabetical order, three of the following four letter-cluster pairs are alike in a certain way and thus form a group. Which is the one that does not belong to that group? (Note: The odd man out is not based on the number of consonants/vowels or their position in the letter-cluster.)
KD – HB
Check the letter-by-letter shift used to obtain the second cluster from the first in each pair.
GJ → FI: G − 1 = F and J − 1 = I, so both letters shift back by 1.
JK → IJ: J − 1 = I and K − 1 = J, so both letters shift back by 1.
CA → BZ: C − 1 = B and A − 1 = Z (wrap around), so both letters shift back by 1.
KD → HB: K − 3 = H and D − 2 = B, so the two letters shift back by different amounts (3 and 2).
Three pairs follow a uniform −1 shift; only KD – HB breaks the rule.
Hence, the odd pair is KD – HB.
