Show answer
Answer: C. The metaverse is a network of connected 3D virtual worlds that many users can enter at the same time through avatars. Users can own and trade virtual items such as digital land or goods, often recorded as NFTs.
Watch for: 'Virtual matrix' sounds techy and fits 'virtual worlds', but the standard term is metaverse.
Why the other options are wrong
- A. Wrong because big data analytics is about studying large data sets, not virtual worlds.
- B. Wrong because cryptography is about securing information with codes.
- D. Wrong because 'virtual matrix' is not a standard term for this idea.
