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 :: ?​
# : MRN :: HMI : %

Given: # : MRN :: HMI : %

Logic: 1st three letter - 3 and 3rd three letter - 3 place.

Now, we check each options.

Option (a): # = JIQ, % = FDJ (Not Follow)

J - 3 $$\neq$$​ M, I - 3 $$\neq$$​ R, Q - 3 = N

H - 3 $$\neq$$​ F, M - 3 $$\neq$$​ D, I - 3 $$\neq$$​ J

Option (b): # = KLJ, % = KHI (Not Follow)​

K - 3 $$\neq$$​ M, L - 3 $$\neq$$​ R, J - 3 $$\neq$$​ N

H - 3 $$\neq$$​ K, M - 3 $$\neq$$​ H, I - 3 $$\neq$$​ I

Option (c): # = LPR, % = JHG (Not Follow)​

L - 3 $$\neq$$ M, P - 3 $$\neq$$ R, R - 3 $$\neq$$​ N

H - 3 $$\neq$$ J, M - 3 $$\neq$$​ H, I - 3 $$\neq$$ G

Option (d): # = PUQ, % = EJF (Follow)​

P - 3 = M, U - 3 = R, Q - 3 = N

H - 3 = E, M - 3 = J, I - 3 = F

Thus, correct option is (d).
