Explanation:
Option C is correct because distributed ledger technology (DLT) fundamentally operates on a consensus mechanism where multiple nodes in the network must agree on the validity of transactions and the current state of the ledger. This consensus ensures data integrity and prevents double-spending or fraudulent transactions.
Option A is incorrect because DLT, particularly proof-of-work blockchain systems (like Bitcoin), is notoriously energy-intensive due to the computational power required for mining and transaction verification. While some newer DLT systems use less energy-intensive consensus mechanisms (like proof-of-stake), the statement that DLT "requires minimal energy" is generally inaccurate.
Option B is incorrect because one of the core features of DLT is immutability. Once a transaction is recorded on a distributed ledger and validated through consensus, it cannot be easily deleted or altered. This immutability is a key security feature that prevents tampering and ensures trust in the system.
