Every step explained - no skipped algebra.
The Earth rotates on its axis once approximately every 24 hours. This continuous spinning causes different parts of the Earth to face towards or away from the Sun during the day, creating the cycle of day and night. When a part of the Earth faces the Sun, it experiences daylight, and conversely, when it faces away, nighttime occurs. This daily rotation is the fundamental reason for the alternation of day and night globally.
Final Answer: Option B - Day and night
