Answer:
B) each expense account will be credited.
Step-by-step explanation:
Revenue and expense accounts are temporary accounts since they basically show how the company operated during the year and must be rest for the next accounting period.
First all revenue and expense accounts must be closed to an income summary account. Expense accounts are closing by crediting them and revenue accounts are closed by debiting them.
Then the income summary account and the dividends account must be closed to retained earnings. The only "permanent" account in this sequence is retained earnings that is part of shareholders' equity.
