C Correct answer
Explanation

Image formed by pinhole camera is real, upside down i.e. inverted and a clear or a sharp one. (size of the pinhole should be quite small). Simply explained, it is a light proof box with a small hole in one side. When sunlight passes through the tree leaves, we are able to see the circular images of the sun. During the same, it is the gaps in the leaves which acts as pinhole camera and produce an image of sun.Light is required for image formation so no image will be formed during night with no source of light
