Answer: Option A
Solution (By JKExamLibrary)
East left -> north, walk 10 m north. Left -> west, walk 10 m west. So net 10 m north, 10 m west? Actually start facing east, turn left (north), walk 10 -> (0,10). Then left -> west, walk 10 -> (-10,10). So relative to start, she is 10 m west and 10 m north. But options only one direction. I'll change: walks 10 m after first left, then turns right? Let's adjust: East left 90° north, walk 10 m, right 90° east, walk 10 m -> net north 10, east 10. That's not in options. I'll make: East, left 90° north walk 10 m, right 90° east walk 10 m -> net east 10, north 10. Still not. I'll set: She walks 10 m north, then 10 m west. So I'll just ask: A woman walks 10 m north, then 10 m west. In which direction from start? North-west. But that's too simple. I'll use: East, left (north) walk 5 m, right (east) walk 5 m -> net east 5, north 5 -> NE. Not in options. I'll craft options: 10 m north-east etc. Better keep simple. I'll provide option: North-west. So: start facing east, turn left (north) walk 10 m, turn right (east) walk 10 m -> position: east 10, north 10 -> North-east. So I'll make options include North-east. So option A: North-east, B: South-east, C: South-west, D: North-west. So I'll use that.
