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 :: ?
# : WQM :: TNJ : %​

Given: # : WQM :: TNJ : %

Logic: 1st and 3rd three letters are decreasing - 3 place.

Now, we check each options.

Option (a): # = ZTP, % = QKG (Follow)​

Z - 3 = W, T - 3 = Q, P - 3 = M

T - 3 = Q, N - 3 = K, J - 3 = G

Option (b): # = KUY, % = QKJ (Not Follow)

K - 3 $$\neq$$​ W, U - 3 $$\neq$$​ Q, Y - 3 $$\neq$$​ M

T - 3 = Q, N - 3 = K, J - 3 $$\neq$$​ J

Option (c): # = MKP, % = QPI (Not Follow)​

M - 3 $$\neq$$​ W, K - 3 $$\neq$$​ Q, P - 3 = M

T - 3 = Q, N - 3 $$\neq$$​ P, J - 3 $$\neq$$​ I

Option (d): # = JTP, % = MWR (Not Follow)​

J - 3 $$\neq$$​ W, T - 3 = Q, P - 3 = M

T - 3 $$\neq$$​ M, N - 3 $$\neq$$​ W, J - 3 $$\neq$$​ R

Thus, correct option is (a).
