Self-study
Despite the enormous number of transactions processed daily by banks nowadays, if a customer's bank account is accidentally credited with a large sum of money, it is extremely unlikely that the error will not be detected by the bank's internal audit procedures.
Summarize Argument
The author states that if a bank customer accidentally receives a large deposit of money, the bank will almost certainly detect the error, even though banks process a huge number of transactions. No evidence is provided for this claim.

Which one of the following, ██ █████ ████ ████████ ████████ ███ █████ ██████
a
Banks initially process ███ ████████████ █████ ███ ███ ██ ████████ █████████ ███ ████ ███ █ █████████ ███ ██ ████████ ██ ████████████ █████ █████████████
Since banks double-check large transactions, they’re likely to catch an accidental large credit. This provides some evidence to support the author's claim.

As far as we know, customers aren’t involved in these accidental credits. So this doesn't explain how accidental deposits would be caught.
c
Banks are required ██ ███ ██ ████ ████ ████████ █ ███████ █████████ █████████ █████ ███████████ ██ ███ ████████ ██████
This doesn’t explain how those large accidental credits would be caught by the bank. If anything, this shifts responsibility to the customer to catch such mistakes.
d
The average ratio ██ ████ ████████ ██ ████████ ████████ ███ ██████ █████████ ████ ███ ████ ███ ██████
Even if that ratio has increased, we don't know how effective these auditors used to be, or how much their efficacy has improved. This doesn't provide enough information to be supportive.

The development of █████████████ ████████ ████████ ███ ████████ ████ █████████ ██████ ██████████ ██ █████████ ██ ████████ ████████
As far as we know, accidental credits to customer accounts have nothing to do with hackers. That makes information about hackers irrelevant.
