The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Position of the Sun and Earth:** At noon, the Sun is directly overhead, and the part of the Earth facing the Sun experiences the least distance from it. 2. **Scattering of Light:** Scattering of light occurs when sunlight passes through the Earth's atmosphere. The amount of scattering depends on the distance the light travels through the atmosphere. 3. **Minimum Distance at Noon:** At noon, the distance between the Earth and the Sun is at its minimum. This means that sunlight travels a shorter distance through the atmosphere compared to morning or evening. 4. **Effect of Scattering on Color Perception:** Different colors of light scatter differently. Blue light, which has a shorter wavelength, scatters more than red light, which has a longer wavelength. 5. **Conclusion:** Since the distance is minimum at noon, there is less scattering of light. Therefore, all colors of white light reach the observer with less interference, making the Sun appear white. 6. **Final Answer:** At noon, the Sun appears white because light is least scattered. ---
