AI Explanation
The correct answer is D) rotation. The spinning motion of a planet around its axis is called rotation. This refers to the planet's continuous spin or turning movement around its own center or axis, which results in the alternation of day and night on the planet's surface. The other answer choices are incorrect because: A) Revolution refers to the orbital motion of a planet around the sun, not its spinning motion around its own axis. B) Orbit also refers to the orbital motion of a planet around the sun, not its rotation. C) Space motion is not a commonly used term to describe the spinning of a planet around its axis.
