The correct answer is A. Nominal accounts.
Nominal accounts are temporary accounts that are used to record revenues and expenses for a specific accounting period. They are closed to retained earnings at the end of the accounting period.
Real accounts are permanent accounts that are used to record assets, liabilities, and equity. They are not closed at the end of the accounting period.
Cash accounts are asset accounts that are used to record cash receipts and disbursements.
Bank accounts are asset accounts that are used to record money that is deposited in a bank.
