Final answer:
A check written on an account does not immediately alter the available balance at the bank due to processing time required for the check to clear. Meanwhile, electronic transfers, cash withdrawals, and cash deposits usually result in immediate adjustments to the account's available balance.
Step-by-step explanation:
The correct answer to the question 'Which of the following does not result in immediate changes in the available balance at the bank?' is A. A check written on the account. When you write a check, there may be a delay in the reflection of the available balance in the account until the check is presented for payment and processed by the bank. This is in contrast with B. Electronic transfers, C. Cash withdrawals, and D. Deposits of cash, which typically result in immediate changes to the available balance in a bank account.
Electronic transfers are processed very quickly, sometimes instantaneously, through modern banking systems. Cash withdrawals and deposits involve physical transactions which are immediately recorded by the bank. As for checks, until they are cleared, the bank does not guarantee the availability of funds, and hence, the account balance does not immediately reflect this potential outgoing amount.
