Augmented reality can be described as:

Augmented reality (AR) refers to technology that enhances or supplements the real world with digital information or images. This means that when a user looks at their real environment through a device, such as a smartphone or AR glasses, digital elements are superimposed onto the physical world they see. This layering of digital information provides users a richer experience where they can interact with both the physical and the virtual simultaneously.

This aligns with the fundamental concept of AR, which is distinct from other technologies like virtual reality that create completely immersive digital environments. In augmented reality, the focus remains on enhancing the user's perception of their real-world surroundings rather than isolating them from it.

Other options suggest concepts that do not accurately reflect the nature of augmented reality. For instance, the description of a virtual world created entirely by computer graphics fits virtual reality instead of augmented reality, which integrates real-world elements.
