Solution
The correct option is B direction keeping the pole-star to his left
Pole star's position with respect to rotating earth never changes and it always points to the north direction. Thus, if the person keeps the pole star to his left, he can be sure of walking in the eastern direction in which his village is located. Polestar was used widely for navigation in ancient and medieval times due to its stable position.
