Show answer & explanation
Correct answer: C
Key insight: the clockwise and counterclockwise rotations cancel, giving a net rotation of 0°.
Step 1: Start facing south-east.
Step 2: Turn 45° anti-clockwise → face east.
Step 3: Turn 135° clockwise → face south-west.
Step 4: Turn 90° anti-clockwise → face south-east.
Net rotation: counterclockwise 45° + 90° = 135°, clockwise = 135°, so net = 0°.
Final direction: south-east.
