Pick up the correct statement from the following: A. North end of the polar axis is known as North Pole B. South end of the polar axis is known as South Pole C. Point where polar axis when produced northward intersects the celestial sphere, is known as north celestial pole D. All the above

The correct answer is D. All the above.

The Earth’s axis is an imaginary line that runs through the center of the Earth from the North Pole to the South Pole. The North end of the polar axis is known as the North Pole, and the South end of the polar axis is known as the South Pole. The point where the polar axis intersects the celestial sphere is known as the north celestial pole.

The celestial sphere is an imaginary sphere that surrounds the Earth. The stars appear to be fixed on the celestial sphere, but they are actually moving in space. The north celestial pole is the point in the sky directly above the North Pole. The south celestial pole is the point in the sky directly above the South Pole.

The north celestial pole is currently marked by the star Polaris, which is also known as the North Star. Polaris is a very bright star, and it is easy to find in the night sky. The south celestial pole is not marked by any bright stars, so it is more difficult to find.

The north celestial pole and the south celestial pole are important points in astronomy. They are used to define the Earth’s coordinates, and they are used to track the movement of the stars.
