Concept:Odd-letter questions are solved by checking the position gaps between letters in the alphabet.Explanation:Convert each letter to its alphabet position.FHJ→6,8,10; gaps are +2,+2.LNQ→12,14,17; gaps are +2,+3.JLN→10,12,14; gaps are +2,+2.NPR→14,16,18; gaps are +2,+2.Only LNQ has unequal gaps.
Answer:LNQ is the odd one, so option B is correct.
