At noon, the sun is at top and the light rays coming from the sun have to travel lens distance hence, all colours get scattered very less even blue and violet.

Explanation:
Scattering of Light:
- When sunlight enters the Earth's atmosphere, it interacts with the particles present in the atmosphere.
- The particles in the atmosphere scatter the sunlight in different directions.
Colors in White Light:
- White light is a combination of all the colors of the visible spectrum, including red, orange, yellow, green, blue, indigo, and violet.
- When white light passes through a medium, it can be separated into its constituent colors.
Scattering of Colors:
- The scattering of light depends on the wavelength of the light. Shorter wavelengths are scattered more than longer wavelengths.
- Blue light has a shorter wavelength compared to red light, so it is scattered more by the particles in the atmosphere. This is why the sky appears blue.
Noon Sunlight Appearance:
- At noon, when the sun is at its highest point in the sky, the sunlight has to pass through the least amount of atmosphere to reach the observer.
- This means that there are fewer particles in the atmosphere to scatter the sunlight.
- As a result, the blue light, which is scattered the most, is scattered away, leaving behind the other colors of the spectrum.
- The scattered blue light is what gives the sky its blue color, but at noon when it is least scattered, the sun appears white.
Therefore, the correct answer is option 'A' - light is least scattered at noon, causing the sun to appear white.
