What is augmented reality (AR)?

• A. Technology that superimposes images and information onto a live view from a smartphone or tablet.
• B. A technology that replaces real world with 3D models.
• C. Software that edits photos after capture.
• D. Streaming video overlays in broadcast.

Answer: (A)

Augmented reality works by blending digital content with the real world in real time, using a device’s camera to provide a live view and then superimposing images, information, or 3D objects onto that view. This is exactly what the described option captures: technology that overlays digital content onto the live view from a smartphone or tablet, so you see both the real surroundings and the added elements together.

The other descriptions point to different ideas. Replacing the real world with 3D models describes virtual reality, where you’re immersed in a fully digital environment. Editing photos after capture is just post-processing, not live augmentation. Streaming video overlays in broadcast involves overlays on video content, not interactive augmentation of a live camera feed.
