Show answer & explanation
Correct answer: C
Vivek moves 30m North, then 40m East, then 20m South, and finally 40m West.
Horizontal movements cancel out: 40m East - 40m West = 0m.
Vertical displacement: 30m North - 20m South = 10m North.
Consequently, his final distance from the original position is exactly 10 metres.
Final Answer: Option 3
