LX – WK
- B.

Attempted by 84 students.
Show answer & explanation
Correct answer: B
1. Analyze the positional relationship between the left and right letter pairs in each option.
2. In options A, C, and D, the logic is to subtract 1 from the alphabetical value of each letter and then reverse their positions (Cross Pattern). For example, in LX -> WK: L(-1) = K and X(-1) = W; writing them in reverse gives WK.
3. In option B (NO - MN), the logic is a direct subtraction without reversal: N(-1) = M and O(-1) = N, resulting directly in MN. Because it lacks the position swap, it is the odd one out.
Final Answer: Option B
