    B. Diffraction is what causes the water to look blue by it "bouncing off" the light waves from the sky. This is why the water and sky are the same color.

    B. Diffraction

    Explanation:

    We are given that a person flying in a plane over Easter island notices that the water around the island appear bluer than the surrounding water.

    We have to find the property by which light waves causes the water to be a different color to the observer.

    Diffraction: It is a phenomena in which bending of light around the corner of an obstacle or aperture into a region of geometrical shadow of an obstacle.

    Due to diffraction the light waves bouncing off from the sky and water appears blue and causes the water to be different color to the observer.

    Hence, option B is true.
