Understanding the Robot's Movement
When the robot is initially facing South, it has a specific orientation. To understand its new direction after the movement, we need to analyze the effect of a quarter turn clockwise.
Initial Direction
- The robot starts facing South.
Quarter Turn Clockwise
- A quarter turn means the robot will rotate 90 degrees to its right.
Direction Changes with Each Turn
- Let's visualize the directions:
- Facing South (0 degrees)
- A quarter turn clockwise (90 degrees) will change the orientation:
- From South to West (90 degrees)
Conclusion
- After making a quarter turn clockwise from South, the robot is now facing West.
Thus, the correct answer is option 'C': West.

Quarter turn anti-clockwise = 90° → South → East
Half turn clockwise = 180° → East → West
Half turn clockwise = 180° → East → West
