Detailed Solution

Concept- As seen from the Earth's surface, the position of a pole star (or polaris or polaris) appears fixed. When viewed from the world's equator, it is roughly overhead. It is frequently associated with the constellation "Ursa major." The fundamental concept in this question is the rotation of the earth, from west to east.
Now, when we apply this to the provided question, we obtain
Because of the rotation of the Earth, the sky above appears to rotate. Because the Earth rotates west to east, the apparent fixed stars move east to west. However, because the Earth's axis of revolution passes through the pole star, it is that moment around which the sky spins, and therefore the pole star seems stationary.
Hence, the correct answer option 2.
