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 ::?
# : MLI :: LKH : %​

Given:

# : MLI :: LKH : %​

Lets check all options;

Option a) # = FRL, % = QHE

FRL → MLI

F + 7 → M
R – 6 → L
L – 3 → I

LKH → QHE

L + 7 → Q
K – 3 → H
H – 3 → E  (Not follow same pattern)

Pattern: +7, –3, –3

Option B:  # = UIL, % = IXC 

UIL → MLI
U –  8 → M
I + 3 → L
L – 3 → I

 LKH → IXC
L – 3 → I
K + 13 → X
H – 5 → C (Not follow same pattern)

Option C: # = POL, % = IHE

 POL → MLI
P – 3 → M
O – 3 → L
L – 3 → I

% = LKH → IHE
L – 3 → I
K – 3 → H
H – 3 → E

Option D:  ​# = FOL, % = QHE

 FOL → MLI
F + 7 → M
O – 3 → L
L – 3 → I

LKH → QHE
L + 5 → Q
K – 3 → H
H – 3 → E

Thus, correct option is (c).
