A Correct answer
Explanation

Day and night are caused by Earth's rotation on its axis. As Earth spins, different parts face the sun (daylight) or face away (nighttime). One complete rotation takes about 24 hours. Revolution refers to Earth's year-long orbit around the sun, not the daily cycle of day and night. 'Evolution' is a biological process unrelated to Earth's movements.
