- A. disperson effect
- B. scattering
- C. reflection
- D. transmission
Explanation
The sky or water in the sea looks blue because the light of long wavelength gets absorbed, and light of short wavelength (blue light) gets scattered by water and falls on cornea of our eyes.

About Solutions and Colloids
Solutions are described using molarity, molality, normality, mole fraction, percentage concentration and parts per million. Coverage also includes vapour-pressure lowering, boiling-point elevation, freezing-point depression and osmotic pressure, then distinguishes true solutions, colloids and suspensions by particle size, stability, light scattering and settling.
