Which of the following best describes static objects in Unity?

Static objects in Unity are characterized by their fixed position in the game environment, meaning they do not move throughout gameplay. This immobility allows them to take advantage of lightmapping, which is a process that pre-calculates the lighting for these objects. By using lightmaps, static objects can display detailed and optimized lighting effects without the need for real-time calculations, thus improving performance.

In contrast, dynamic objects, which are not static, are capable of moving or changing position during gameplay, and require more complex lighting calculations to ensure their lighting responds accurately in real-time. Static objects, through their fixed nature, allow for better performance in scenes where not all objects need to be calculated for lighting dynamically, maximizing rendering efficiency.

The other options don’t accurately capture the essence of static objects: while they indeed do not require constant lighting calculations like dynamic ones do, they specifically benefit from lightmaps, which makes option C the most appropriate descriptor.
