To solve the problem, we need to track Ravi's movements and determine his final facing direction after following the given steps:
- Ravi starts by walking 10 meters north. Initially, he is facing north.
- Then, he turns right. From facing north, turning right would mean Ravi is now facing east.
- Next, Ravi walks 5 meters east.
- Ravi turns right again. While facing east, turning right would turn him to face south.
- Finally, Ravi walks 10 meters south.
After these movements, Ravi is facing South.
Therefore, the correct answer is: South
