Which of the following letter-clusters should replace # and % so that the pattern and relationship followed between the letter-cluster pair on the left side of :: is the same as that on the right side of ::?
# : OLR :: PMS : %​

# : OLR :: PMS : %​

Option a). # = JGM, % = URX

Logic: Each letter moves forward by +5 in the alphabet.

J + 5 → O, G + 5 → L, M + 5 → R 

P + 5 → U,  M  + 5 → R, S  + 5 → X

This is the only pair where both sides follow the identical +5, +5, +5 letter shift.

Other Options:

Option B (MKI → OLR):
M→O (+2), K→L (+1), I→R (+9) →Inconsistent shifts

Option C (KLM → OLR):
K→O (+4), L→L (+0), M→R (+5) →Inconsistent shifts

Option D (LKP → OLR):
L→O (+3), K→L (+1), P→R (+2) →Inconsistent shifts

Thus, correct option is (a).
