In the Northern Hemisphere, the polestar, also known as Polaris, appears nearly fixed in the sky towards the north. As the person is standing in a desert and wants to reach a location 5 km east of his current position, he should keep the polestar to his left as he walks. This would ensure that he is heading roughly in an easterly direction, towards his village. Therefore, option (c) is the correct choice.

Understanding the Polestar's Position
The Polestar, or North Star, is located almost directly above the North Pole. In the Northern Hemisphere, it serves as a reliable reference point for navigation.
Determining Directions
- When standing in the desert and facing the Polestar, you are facing true north.
- Your village is situated 5 km east of your current position.
Walking Towards the Village
- To reach the village, you need to walk towards the east.
- If you are facing north (towards the Polestar), east is to your right.
Keeping the Polestar to Your Left
- By keeping the Polestar to your left, you will effectively position yourself to head east.
- This means you will turn 90 degrees to the right from facing the Polestar, orienting your path towards the east.
Conclusion
- Walking in the direction that keeps the Polestar to your left allows you to move directly toward your village.
- Therefore, the correct answer is option 'C': direction keeping the Polestar to his left.
By using the Polestar as a navigational aid, you can successfully find your way east to your village.
