Explanation:
To form a shadow, the following components are required:
1. Source of light: A shadow is formed when light rays from a source hit an object and are blocked, causing a dark region to appear behind the object.
2. Opaque object: An opaque object is necessary to block the path of light, preventing it from reaching the screen or any other surface.
3. Screen or surface: The screen or surface is where the shadow is formed. It is the area where the light is blocked by the opaque object, resulting in a dark region.
However, a lens is not required for the formation of a shadow. A lens is a transparent object that can refract or bend light. Since a shadow is formed by blocking light, the presence of a lens would not have any effect on the formation of a shadow.
Therefore, the correct answer is D: Lens.
