The image beneath displays a duck floating in a pond.

Why does it seem like there is an additional duck head in the water?

a. The pond's bottom absorbs the light and subsequently projects it towards the surface in the form of an image.

b. The molecules in the atmosphere bend the light, causing it to separate into two images.

c. The duck disperses the light, creating numerous small refractions that converge into an image.

d. The pond's water reflects sunlight, creating a mirrored image.
