The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Question**: The question asks who discovered that galaxies are receding away from one another. This refers to the observation that galaxies are moving apart as the universe expands. 2. **Identifying the Options**: The options provided are: - Option 1: Plato - Option 2: Kepler - Option 3: Edwin Hubble - Option 4: Albert Einstein 3. **Analyzing Historical Context**: - Plato was a philosopher and did not contribute to the field of astronomy in this context. - Kepler was known for his laws of planetary motion but did not discover the expansion of the universe. - Albert Einstein contributed to the understanding of the universe with his theory of relativity, but he did not specifically show that galaxies are receding. 4. **Identifying the Correct Answer**: - Edwin Hubble, in the 1920s and 1930s, conducted observations that led to the conclusion that the universe is expanding. He discovered that galaxies are moving away from each other, which is now known as Hubble's Law. 5. **Conclusion**: The correct answer to the question is Edwin Hubble (Option 3). **Final Answer**: Edwin Hubble ---
