Camera obscura is which of the following?

Light from the outside passes through a tiny opening and projects an inverted image onto a surface inside a dark space. That surface is typically a wall or screen, which is why projecting onto a wall is the correct description. The image is formed by projection, not by reflection, so it isn’t about a mirror. It isn’t about placing the image into a camera body, which belongs to later camera designs. The wall provides a convenient flat surface to view and study the projected scene, and the inversion happens because light travels in straight lines and crosses at the small hole.
