Answer:
3) Control risk is assessed at below the maximum.
Step-by-step explanation:
When the control risks are assessed at below the maximum it means that the controls are effective regarding the prevention and detection of misstatements in the financial statements.
So if the auditor wants to test the controls, it means that he/she wants to verify the operating effectiveness of the controls.
In other words, apparently the controls show that there are no misstatements regarding the sales transactions, so the auditor wants to check how efficient the controls are.
