Correct option is A
1. **Option (A): CWX-AVZ**
- Comparing the letters:
- C → A (Move 2 steps backward)
- W → V (Move 1 step backward)
- X → Z (Move 2 steps forward)
- Pattern: Symmetric shifts.
2. **Option (B): TXB-QWE**
- Comparing the letters:
- T → Q (Move 3 steps backward)
- X → W (Move 1 step backward)
- B → E (Move 3 steps forward)
- Pattern: Symmetric shifts.
3. **Option (C): REA-ODD**
- Comparing the letters:
- R → O (Move 3 steps backward)
- E → D (Move 1 step backward)
- A → D (Move 3 steps forward)
- Pattern: Symmetric shifts.
4. **Option (D): NVH-KUK**
- Comparing the letters:
- N → K (Move 3 steps backward)
- V → U (Move 1 step backward)
- H → K (Move 3 steps forward)
- Pattern: Symmetric shifts.
By analyzing all options we can say that Option(a) is different from all other.
