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 one out is not based on the number of consonants/vowels or their position in the letter-cluster.)
JE - MK
Check how the second cluster is formed from the first in each pair.
HC - GB: H becomes G and C becomes B, so each letter goes back by 1.
NI - MH: N becomes M and I becomes H, so each letter goes back by 1.
LG - KF: L becomes K and G becomes F, so each letter goes back by 1.
JE - MK: J becomes M, a shift of \(+3\), and E becomes K, a shift of \(+6\), which is not the same rule.
Three pairs use a uniform \(-1\) shift, but JE - MK does not.
Hence, the pair that does not belong to the group is JE - MK.
