Final answer:
While the overall balance sheet might appear balanced, individual account balances can still contain errors. Errors in transactions or fraudulent activity can lead to incorrect individual balances, even in apparent equilibrium.
Step-by-step explanation:
If everything is in balance, it does not necessarily mean that all account balances are correct. While the overall balance sheet might appear to be in equilibrium, individual account balances could potentially contain errors. It is possible for transactions to be misrecorded or for fraudulent activity to occur, which would still allow the overall balance to appear correct if opposing errors cancel each other out. Therefore, the correct statement is: some account balances may be wrong, even if the overall balance appears to be correct.
