Solution

The correct option is C Pinhole-camera images of sun formed by spaces between leaves in canopy.
The elliptical splashes of sunlight on the ground under a tree are called pinhole images, the source of the light is the sun, the dry porous leaves and the gaps between the leaves act as the screen, and the phenomenon is known as the diffraction of lights.
