Show answer & explanation
Correct answer: A
Assign numerical positions to each letter: A=1, B=2, ..., I=9, H=8, J=10, O=15, N=14, P=16, G=7, F=6, C=3, D=4.
Analyze the pattern for each pair:
Option B (ON–PO): (O→P is +1), (N→O is +1).
Option C (GF–HG): (G→H is +1), (F→G is +1).
Option D (CB–DC): (C→D is +1), (B→C is +1).
Compare with Option A:
Option A (IH–JH): (I→J is +1), but (H→H is 0).
Since Option A is the only pair that does not follow the (+1, +1) pattern, it is the odd one out.
Final Answer: Option A
