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 ::?

# : AGJ :: GMP : %​​

Given: # : AGJ :: GMP : %​​

Logic: Letters are increasing by + 4 in English alphabetical order.

Now, we check each options.

Option (a): # = WCF; % = KQT (Follow)

W + 4 = A, C + 4 = G, F + 4 = J

G + 4 = K, M + 4 = Q, P + 4 = T

So option (a) is follow the logic.

Thus, correct option is (a).
