To determine Ravi's final orientation, we must trace his movements and resulting direction changes:
- Ravi begins facing north and walks 10 meters north.
- He then turns right, changing his facing direction from north to east.
- Subsequently, Ravi walks 5 meters east.
- He turns right again, shifting his facing direction from east to south.
- Finally, Ravi walks 10 meters south.
Upon completing these actions, Ravi is facing South.
Consequently, the correct answer is: South
