Answer :
Bank A has the highest possible overdraft fee.
An overdraft fee is charged when a payment or withdrawal from your bank account exceeds the available balance and your bank covers the transaction as part of an overdraft protection service. But in addition to covering the transaction, the bank or credit union then applies the fee.
What happens if you have an overdraft fee?
If you don't bring your balance above zero, the bank may close your account and transfer an unpaid balance to a collection agency. Another form of overdraft protection that banks may offer is an automatic transfer from a linked account to cover a purchase if you don't have enough money in checking.
