How are we able to perceive an object as being the color white?

The picture shows a duck that appears to have its body detached when viewed underwater. Why does the duck's body look detached?

• because the bottom of the pond scatters the light, making the duck's body underwater appear different than the rest of the duck

• because the atmosphere absorbs the sunlight, so it reaches the ducks body underwater slower than the rest of the duck

• because the pond is a different material than the air, and sunlight gets refracted as it travels in and out of the water

• because the duck reflects the light toward its abdomen, making it look different than the rest of the duck
