Which one of the following words/phrases is most appropriately used to denote 'an interoperable network of 3D virtual worlds that can be accessed simultaneously by millions of users, who can exert property rights over virtual items'?
- ABig data analytics
- BCryptography
- CMetaverseCorrect
- DVirtual matrix
Explanation
The description matches the Metaverse — a persistent, interoperable network of 3D virtual worlds accessed concurrently by many users, in which users can own and trade virtual assets (often via blockchain-based tokens like NFTs that confer property-like rights over digital items).
- Big data analytics is about processing very large datasets to extract insights — unrelated to 3D virtual worlds.
- Cryptography concerns secure communication and data protection; it underlies the property-rights layer of the metaverse but is not the term for the virtual world itself.
- Virtual matrix is not an established technical term in this context.
Hence, Metaverse is the correct answer.
