The correct option is D image
When a light rays come and incident on a surface, it bounces back. The bouncing back of light rays is called reflection. The surface in which reflection happens is called the reflecting surface.
A mirror is an object which reflects the light ray. A mirror whose reflecting surface is flat or plane is called a plane mirror. Mirror we used in our home is a plane mirror. If we look into the mirror , we can see our face inside the mirror. What we see inside the mirror is called an image.
Hence, reflection is responsible for the formation of images. We can see the reflected images of trees, buildings etc in a clear water body because it acts as a mirror.
