Answer:
B) An understatement of assets and understatement of revenues
Explanation:
Accrued revenues are revenues that are earned but are still collectible.
That means the adjusting entry should have been:
Debit to Accounts Receivable and
Credit to Revenue
If the company failed to prepare this adjusting entry then the Accounts Receivable will not be recorded and thus will understate the Asset since Accounts Receivable is an Asset.
The same goes for revenue, if not recorded, will understate Revenue.
