Which of the following group of alphabets will best complete the relationship given below?
DFI : MOR :: LNQ : ?

Correct option is C

Logic: +9
Analyze the first pair, DFI : MOR.
D → M: Shift of +9 (D is the 4th letter, M is the 13th letter).
F → O: Shift of +9 (F is the 6th letter, O is the 15th letter).
I → R: Shift of +9 (I is the 9th letter, R is the 18th letter).
So, each letter in DFI is shifted by +9 to get MOR.
Apply the same shift to LNQ.
L → U: Shift of +9 (L is the 12th letter, U is the 21st letter).
N → W: Shift of +9 (N is the 14th letter, W is the 23rd letter).
Q → Z: Shift of +9 (Q is the 17th letter, Z is the 26th letter).
Thus, LNQ becomes UWZ.
Correct answer: (c) UWZ.
