The correct answer is B: in charge of making sure transactions are correct.
Explanation: This statement suggests that the security of the ledger (the record of transactions) increases with the number of miners. Miners validate and confirm transactions on the blockchain, ensuring their correctness and maintaining the integrity of the ledger. Thus, their role is crucial in verifying transactions rather than being involved in personal account changes or functioning as traditional bankers.
