The correct answer is: Blocks of data are locked since they are unalterable.
Explanation: Once a block is added to a blockchain, it’s locked in place due to the cryptographic hash functions that link it to the previous block. This ensures that the data cannot be altered without changing all subsequent blocks, which is highly computationally expensive and practically impossible in a secure network. This immutability feature is what prevents tampering and ensures the integrity of the blockchain.
