To exclude objects from being lit by a light source, those objects must be placed on a specific layer designated for exclusion. Unity allows developers to manage interactions between lights and objects through layers, meaning that by placing objects on a particular layer configured to not receive light, you can efficiently control which objects are affected by lighting in the scene. This method can optimize performance by reducing the number of calculations needed for lighting, particularly in complex scenes with many light sources and objects.

While other options might seem plausible in different contexts, they do not specifically relate to the control of lighting via layers in the same direct way. For example, having objects in a different scene does not inherently influence their exposure to lighting from light sources in another scene. Marking objects as static is used primarily to optimize rendering for performance but does not exclude them from being lit. Similarly, being outside the light’s range pertains more to the physical location of the object relative to the light source rather than an intentional exclusion based on object settings or configuration.
