Answer :
Answer:
b. If control risk is assessed as low, the auditor cannot plan on relying on the controls to increase substantive procedures for account balances
Explanation:
Control risk refers to the possibility of internal controls being unable to detect frauds or material misstatements.
An auditor assumes control risk as high unless enough sufficient appropriate evidence has been obtained suggesting it to be low.
High control risk increases the work of an auditor but a lower control risk does not relieve him of the test of controls. Irrespective of the level of control risk, an auditor shall perform some control procedures.
Substantive procedures are those procedures which are carried out to check transactions and account balances.
If control risks are assessed as low, this indicates client's internal controls are strong and effective and are more reliable. This would reduce the extent of nature, timing and extent of control procedures to be performed by the auditor.
