In the context of digital technologies for entertainment, consider the following statements:1. In Augmented Reality (AR), a simulated environment is created and the physical world is completely shut out.2. In Virtual Reality (VR), images generated from a computer are projected onto real-life objects or surroundings.3. AR allows individuals to be present in the world and improves the experience using the camera of smartphones or PCs.4. VR closes the world, and transposes an individual, providing a complete immersion experience.Which of the statements given above is/are correct?

a1 and 2 only
b3 and 4
c1, 2 and 3
