Consider the following pairs:

Terms sometimes seen in news | Context/Topic

  1. 1.Belle II experiment | Artificial Intelligence
  2. 2.Blockchain technology | Digital/Cryptocurrency
  3. 3.CRISPR-Cas9 | Particle Physics

Which of the pairs given above is/are correctly matched?

  1. A.1 and 3 only
  2. B.2 only
  3. C.2 and 3 only
  4. D.1, 2 and 3
▶ Answer & Explanation

Correct answer: B. 2 only

Blockchain technology is fundamentally a decentralized, distributed ledger system that underpins cryptocurrencies like Bitcoin. The Belle II experiment is a particle physics experiment focused on studying B mesons, not artificial intelligence. CRISPR-Cas9 is a revolutionary gene-editing technology, widely used in biological research and genetic engineering, but not directly in particle physics research itself.
