The correct answer is option 1: North. The pole star, also known as Polaris, is a star that is located very close to the north celestial pole. This means that it appears to be directly above the Earth`s North Pole. Therefore, the pole star indicates the direction of north. It is a helpful navigational tool, as it stays relatively stationary while the other stars appear to move across the sky due to the rotation of the Earth. By finding the pole star and determining its position in relation to other stars or landmarks, one can determine their direction of travel and navigate accurately, especially in the absence of a compass or other navigational tools.
