What is virtual reality (VR)?

• A. A type of social media platform.
• B. A technology that uses a headset to provide a full 360-degree experience in games or videos.
• C. A streaming video service.
• D. A form of digital audio encoding.

Answer: (B)

Virtual reality is a technology that uses a headset to put you inside a computer-generated world. It gives you a full 360-degree view and tracks your head movements, so you can look around and feel like you’re really there, often with controllers to interact. This immersive, headset-driven experience is what makes VR ideal for games or videos. The other options don’t fit: a social media platform isn’t about immersive environments, streaming video is just watching content online, and digital audio encoding relates to sound, not visuals. So the description that matches VR is the headset delivering a full 360-degree immersive experience in games or videos.
