Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1 i.e. 2, 4, 1, 3.

Logical flow:

  • Sentence 2 defines what blockchain is (the core idea).
  • Sentence 4 explains how it functions (distribution of ledger copies).
  • Sentence 1 gives the common network type (P2P) used in such systems.
  • Sentence 3 states the resulting benefit (security and transparency).

Correct sequence: 2 → 4 → 1 → 3

Final Passage:
Blockchain technology, at its core, is a distributed ledger that maintains a decentralized record of transactions. It functions by distributing copies of the ledger across a vast network of computers. The most prevalent of these is the peer-to-peer (P2P) network, where no single entity controls the entire system. This decentralized structure ensures security and transparency by requiring network consensus for any new record to be added.

Hence, the chosen option will be correct.
