Consider the following pairs:

Terms sometimes seen in news	Context/Topic
1. Belle II experiment	Artificial Intelligence
2. Blockchain technology	Digital/Cryptocurrency
3. CRISPR – Cas9	Particle Physics

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

The correct answer is 2 only.

Let us analyze each pair given in the table step-by-step to check if it is correctly matched:

1. Belle II experiment — Particle Physics:
The Belle II experiment is an international particle physics experiment designed to study the properties of B mesons (heavy particles containing bottom quarks) and search for physics beyond the Standard Model. It is located at the KEK accelerator complex in Tsukuba, Ibaraki Prefecture, Japan. In the table, it is incorrectly matched with "Artificial Intelligence". Thus, pair 1 is incorrect.

2. Blockchain technology — Digital/Cryptocurrency:
Blockchain technology is a decentralized, distributed ledger system that records transactions across multiple computers. It forms the foundational technology behind digital currencies and cryptocurrencies like Bitcoin and Ethereum. In the table, it is correctly matched with "Digital/Cryptocurrency". Thus, pair 2 is correct.

3. CRISPR – Cas9 — Gene Editing/Biotechnology:
CRISPR-Cas9 is a groundbreaking gene-editing technology that allows scientists to alter DNA sequences and modify gene function within living organisms. In the table, it is incorrectly matched with "Particle Physics". Thus, pair 3 is incorrect.

Comparing our findings with the options provided, only pair 2 is correctly matched.
