Final answer:
The best example of augmented reality from the choices provided is an app that allows shoppers to virtually place furniture in their home to see how it looks, which is option A.
Step-by-step explanation:
The question "Which of the following is the best example of augmented reality?" is best answered by considering what augmented reality (AR) involves. AR is a technology that superimposes a computer-generated image on a user's view of the real world, providing a composite view. It enhances one's current perception of reality.
The options given include several forms of technology, but only one fits the definition of AR. Choosing an answer that aligns with the utilization of AR, we find that option A, an app that allows shoppers to virtually place furniture in their home to see how it looks, is a prime example of augmented reality in action. This app lets users preview virtual items in the context of their physical spaces.
While the other options involve technology, they do not fall under the category of AR. Self-driving cars, online banking systems, digital personal assistants, and retail analytics either involve automation, machine learning, or other forms of digital assistance but do not augment the real-world environment with virtual data.
