The correct Answer is:
To solve the question regarding the distance between the Earth and the Sun in astronomical units (AU), follow these steps: ### Step-by-Step Solution: 1. **Understand the Definition of Astronomical Unit (AU)**: - An astronomical unit is defined as the average distance from the Earth to the Sun. 2. **Identify the Distance**: - By definition, the distance from the center of the Sun to the center of the Earth is equal to 1 astronomical unit (AU). 3. **Evaluate the Options**: - The options provided are: - 1 AU - 4.2 AU - 14.5 AU - 21 AU 4. **Select the Correct Answer**: - Since we established that the distance from the Earth to the Sun is defined as 1 AU, the correct answer is option A, which is 1 AU. 5. **Conclusion**: - Therefore, the distance between the Earth and the Sun in astronomical units is 1 AU. ### Final Answer: The distance between the Earth and the Sun is **1 astronomical unit (AU)**. ---
