Beth's bank charges a service fee on a regular checking account for ea

Beth's bank charges a service fee on a regular checking account for each month in which the balance on the account falls below 100$ at any time during the month, did the bank charge a service fee on Beth's regular checking account last month?

1. During last month, a total of 1000$ was withdrawn from Beth's regular checking account.

2. At the beginning of last month Beth's regular checking account balance was $500

I thought because we don't know when exactly the balance was viewed, because there is no date in particular, and the cash might be withdrawn before viewing the balance, during which there will be no service charge or there will be a service charge if the balance was viewed after withdrawing.........

Is this because of above reason the answer is E???Please help
