Question

according to this text, \the more miners there are, the more secure the ledger.\ based on this, you can infer that miners are
a expected to have access to bitcoin.
b allowed to change personal accounts.
c qualified to be real accountants or bankers.
d in charge of making sure transactions are correct.

Explanation:

To solve this, we analyze each option:

• Option A: The statement about miners and ledger security doesn't imply they need access to Bitcoin.
• Option B: Miners aren't about changing personal accounts; ledger security is different from account modification.
• Option C: Being a miner doesn't mean they qualify as accountants/bankers; the context is about ledger security.
• Option D: If more miners make the ledger more secure, miners likely verify transactions (ensure correctness) to secure the ledger.

Answer:

D. in charge of making sure transactions are correct
