At the end of an accounting period, certain accounts must be closed to prepare financial statements and reset balances for the next period. The accounts that must be closed are temporary accounts, which include all income statement accounts (revenues, expenses, and gains/losses).

Why Option A (Income statement accounts) is Correct:

Income statement accounts (revenues, expenses, gains, and losses) are temporary accounts that track financial performance for a specific period.

At the end of the period, these accounts are closed to the retained earnings account to reset them to zero for the next period.

Why Other Options Are Incorrect:

Option B (Balance sheet accounts):

Incorrect because balance sheet accounts (assets, liabilities, and equity) are permanent accounts that carry their balances forward to the next period.

Option C (Permanent accounts):

Incorrect because permanent accounts include all balance sheet accounts, which are never closed.

Option D (Real accounts):

Incorrect because real accounts refer to balance sheet accounts (assets, liabilities, and equity), which remain open.

COSO Internal Control – Integrated Framework: Recommends proper financial reporting controls, including account closures.
