Show answer & explanation
Correct answer: B
Key idea: each direction is rotated 135° clockwise.
Step 1: Represent directions as angles: North = 0°, East = 90°, South = 180°, West = 270°, North‑West = 315°.
Step 2: From the given mappings (North → South‑East, East → South‑West, South → North‑West, West → North‑East) each direction is increased by 135°.
Step 3: Apply the same rotation to North‑West (315°): 315° + 135° = 450° ≡ 90°, which corresponds to East.
Conclusion: North‑West becomes East.
