• B. Temperature of the sun
• C. Humidity in the atmosphere
• D. None of these

Answer 1

The correct option is A

Of the scattering of light

Explanation for correct option:626a205a5641b5f9aa063d2c626a205a5641b5f9aa063d2c:

1. Sun looks reddish during sunrise and sunset because of the scattering of light.
2. Red colour has the longest wavelength so it scatters less as compared to other light so it reaches the human eye when the sun is at the horizon at the time of sunrise and sunset so it appears reddish.

Explanation for incorrect options:

Option B:

The temperature of the sun is constant throughout therefore it has to do nothing with the red colour in sunrise and sunset

Option C:

Humidity in the atmosphere is also an uncertain factor and water droplets are responsible for dispersing light hence it is also not responsible for the red colour of the sun.

Thus, the correct option is (A).
