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 ::?

# : DGJ :: EHK : %​​

Given pair:

# : DGJ :: EHK : %

Logic: ​Each letter is increasing by +7

Option A: # = MZC, % = LOR

M → +7 → T

Z → +7 → G 

C → +7 →  J  Does not follow the pattern.

W → +7 → D  

Z → +7 → G 

C → +7 → J Does not follow the pattern

W→ +7 →D

Z→  +7 → G

C→ +7 →  J

and 

E→ +7 → L

H → +7 → O

K → +7 → R

The % = LOR part follows a +7 shift, which matches the pattern correctly.

Thus the correct answer is: Option C
