• C. Absorption of light by water molecules present in the atmosphere
• D. Dispersion of light by air molecules present in the atmosphere

Answer 1

The correct option is A

Dispersion of light by water droplets present in the atmosphere

Rainbows are formed because of dispersion of light by the water droplets present in the atmosphere. When the white light passes through the water droplets suspended in the atmosphere, it is dispersed into its seven constituent colors which we call as a rainbow.
