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 :: ?
# : QKS :: NHP : %

Information Given:
# : QKS :: NHP : %

Logic: +5 each letter in alphabetically.

= LFN

L → Q = +5
F → K = +5
N → S = +5

Same pattern (+5 each letter).

Apply same to NHP:

N +5 → S
H +5 → M
P +5 → U

Result = SMU

Thus % = SMU.

= LFN, % = SMU

Final Correct Option:
(C)
