Explanation:

To determine why the celestial sphere appears to turn once daily, we analyze each option:

• "the Earth is going around the Sun" describes Earth's revolution (yearly), not daily rotation.
• "everything in the universe turns around the Earth" is geocentric (incorrect, outdated model).
• "of precession" refers to a slow, long - term change in Earth's axis, not daily motion.
• "of the phases of the Moon" is related to lunar cycles, not daily celestial sphere motion.
• "the planet on which we live is rotating" (Earth's rotation) causes the apparent daily rotation of the celestial sphere as we observe from Earth.

Answer:

the planet on which we live is rotating.
