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

Correct option is A

Option (a) 2, 4, 1, 3 is the correct order of the given sentences.
Explanation (why this order is correct):
• 2 should start because it defines blockchain as a distributed, decentralized ledger.
• 4 logically follows: “It functions…” explains how blockchain works (ledger copies distributed across computers).
• 1 comes next because “these” refers to the networks implied by the distributed system, and it introduces the most prevalent type—P2P—explaining no single controller.
• 3 concludes by explaining the result/benefit of decentralization—security and transparency through consensus for new records.
