What file formats are commonly used for 3D models in Unity?

The correct answer is based on the types of file formats that Unity supports for importing and utilizing 3D models within a project. FBX, OBJ, and 3DS are all widely recognized formats in the realm of 3D modeling and are compatible with Unity.

FBX is particularly favored because it can store a wide range of data, including meshes, textures, and animations, making it a versatile choice for importing complex models into Unity. OBJ is a simpler format that is often used for static models, capturing geometry and texture information, making it adequate for certain applications where advanced features are not necessary. The 3DS format, originating from Autodesk's 3D Studio, is another popular format that has been used historically for 3D models and can still be utilized effectively in Unity for various modeling needs.

In contrast, the other options consist of file formats that do not pertain to 3D modeling files. Formats like PNG, JPEG, and GIF are primarily used for 2D images and textures, making them unsuitable for 3D model representation. HTML, CSS, and JavaScript are web technologies, relevant for web development rather than 3D model storages. Likewise, XML, JSON, and CSV are formats used
