Final answer:
Option C: The transaction for purchasing Ethereum (coins) operates on the Ethereum blockchain. Ethereum is the native coin of its own blockchain platform, distinguishing it from Bitcoin, NFTs, and Solana, which are separate entities.
Step-by-step explanation:
If you purchase Ethereum (coins), the transaction operates on the Ethereum blockchain, since it is a native coin. The correct answer to the question is C.) Ethereum. Bitcoin, while being the most popular cryptocurrency, has its own separate blockchain and is not the platform on which Ethereum transactions occur. NFTs (non-fungible tokens) are unique digital assets that can be bought and sold, but they are not blockchains themselves; they typically reside on a blockchain like Ethereum. Solana is another blockchain platform, but it is distinct from Ethereum and has its own native cryptocurrency, called SOL.
Ethereum is a decentralized blockchain platform that enables the creation and execution of smart contracts. It has its own native cryptocurrency called Ether (ETH). When you purchase Ethereum coins, the transaction is recorded on the Ethereum blockchain, which is a public ledger that stores all the transactions and smart contracts executed on the Ethereum network.
Ethereum blockchain is specifically designed to support the Ethereum network and its native cryptocurrency. Each cryptocurrency has its own blockchain, which ensures the secure and transparent recording of transactions.
