Solution

The correct option is B
It is located in the direction of the axis of Earth

Stars appear to be moving because of Earth's rotation. But, pole star is located in the direction of Earth's axis. So, there is no effect of rotation on the angle of vision between Earth and the pole star. Hence, it does not move as the night passes.
