Show answer & explanation
Correct answer: A
Key idea: track the moves step by step and compute the final displacement from the starting point.
Start by walking 10 km south. Position: (0, -10).
Turn right (west) and walk 5 km. Position: (-5, -10).
Turn 90° clockwise (now facing north) and walk 20 km to reach the office. Position: (-5, 10).
Net displacement from the starting point: 5 km west and 10 km north.
Conclusion: the office is in the north-west direction with respect to the starting point.
Answer: North-west.
