Show answer & explanation
Correct answer: C
Key idea: track your bearing (degrees clockwise from North) as you turn.
Start facing south = 180°.
Turn 30° anticlockwise (left): 180° − 30° = 150°.
Turn 285° clockwise (right): 150° + 285° = 435° → 435° mod 360° = 75°.
Turn 15° clockwise: 75° + 15° = 90°, which is East.
Therefore you are facing East; the direction opposite to East is West. Final answer: West.
