With reference to Web 3·0, consider the following statements: 1. Web 3·0 technology enables people to control their own data. 2. In Web 3·0 world, there can be blockchain based social networks. 3. Web 3·0 is operated by users collectively rather than a corporation. Which of the statements given above are correct?

Answer: D. All three statements about Web 3.0 are correct. WEB 3.0 (sometimes called the 'decentralised web') is the next-generation internet built on blockchain technology, decentralised storage, and crypto/token economics. Key principles: (1) User data control: CORRECT. Web 3.0 envisions users CONTROLLING THEIR OWN DATA rather than tech giants hoarding it. Self-sovereign identity (SSI), decentralised identifiers (DIDs), and verifiable credentials are core Web 3.0 mechanisms. (2) Blockchain-based social networks: CORRECT. Several blockchain-based social networks exist (Lens Protocol, Farcaster, Steemit). They allow users to monetise content via tokens, own their followers/relationships, and avoid central platform censorship. (3) Operated by users collectively: CORRECT. Web 3.0 platforms are often governed by Decentralised Autonomous Organisations (DAOs) where token-holders (users) vote on protocol decisions. This contrasts with Web 2.0 where corporations (Google, Meta, Twitter) unilaterally control platforms. All three statements accurately describe Web 3.0 philosophy.
