Observe the picture below. It shows a duck that appears to have its body detached when viewed underwater. Why does the duck's body look this way? (1 point)
because the duck reflects the light toward its abdomen, so it looks different than the rest of the duck
because the lower portion 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 making it reach the duck's 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
