Four letter clusters have been given, out of which three are alike in some manner and one is different. Select the letter cluster that is different.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. ZDK.
The logic used here is:
Each letter cluster is arranged in the increasing order of the English alphabetical series.
AEI, AEU, and IOU follow the pattern whereas ZDK does not follow the pattern
Hence, option 4 is the odd one out.
