The correct answer is (a) light is least scattered.

Here's why:

The color of the sun as we perceive it from Earth's surface is largely determined by Rayleigh scattering of sunlight by the atmosphere. This scattering is more effective at short wavelengths (blue and violet light). However, the violet light is absorbed by the ozone layer and then re-emitted in all directions, hence we don't see the sky as violet.

At noon, when the sun is at its highest point in the sky, its light has to pass through less atmosphere than at sunrise or sunset. Therefore, less blue light is scattered and the sun appears more white than at other times of the day.

So, the sun appears white at noon because its light is least scattered.
