Which description matches virtual reality?

• A. Use of a computer-based system to create an environment that seems 'real' to one or more of the human senses
• B. A method for data encryption
• C. A protocol for streaming media
• D. A programming language

Answer: (A)

Virtual reality is the use of a computer-based system to craft an environment that seems real to one or more human senses. It typically involves a headset that presents immersive 3D visuals and spatial audio, plus input devices and sensors that track your movements so the scene responds as you move. The core idea is creating a sense of presence in a simulated space, not just delivering media or performing data tasks. The other descriptions refer to things like encrypting data, protocols for streaming media, or a programming language—technologies that solve different problems and do not aim to produce an immersive, real-seeming environment.
