Which of the following refers to a technology with a three-dimensional computer simulation in which a person actively and physically participates? a. wireless fidelity*b. virtual realityc. augmented realityd. agile methodology

B. Virtual reality

Explanation:

In a virtual reality context, the visual and auditory senses of the user are fed by data (images, sounds) from the computer using a goggle and earphones.  That allows the person to be totally cut off her real physical environment and be totally immersed into the world (reality) managed by the computer.

Not to be confused with augmented reality, where the physical reality and perception of it aren't changed... but an additional layer of information is added on top of it.  Like pointing your phone camera to a building and getting information about the building displayed on your phone.

the answer would be 2
