Show answer & explanation
Correct answer: B
Final direction: South-West
Start facing West (270°). Turn 45° clockwise → 270° + 45° = 315°, now facing North-West.
Turn 180° clockwise → 315° + 180° = 495° ≡ 135° (mod 360), now facing South-East.
Turn 270° anti-clockwise → 135° − 270° = −135° ≡ 225° (mod 360), now facing South-West.
Quick method: Combine rotations: +45° +180° −270° = −45°. Starting from West (270°): 270° − 45° = 225° → South-West.
