In the following question, select the related letter cluster from the given alternatives.
UYEI : WG : OQJL :?

Correct option is B

Explanation: To find the related letter cluster, let's break down the pattern:
· UYEI → WG
· The 1st letter (U) and 2nd letter (Y) shift by -1 and -2, respectively, giving us W and G.
· The 3rd letter (E) and 4th letter (I) shift by -2 and -1, respectively, giving us G and W.
· OQJL → ?
· The 1st letter (O) and 2nd letter (Q) shift by -1 and -2, respectively, giving us P and K.
· The 3rd letter (J) and 4th letter (L) shift by -2 and -1, respectively, giving us K and P.
Thus, the related letter cluster is PK.
