Answer: A
Inherent risk is the susceptibility of an area or process to
an error that could be material. Exits out of an authorized
program are an inherent risk as they provide a flexibility
for inserting code to modify or add functionality. The exits
(trap doors) also permit insertion of unauthorized code.
Detection risk (choice B) is the risk that IS auditor's
substantive procedures will not detect an error which could
be material, indivually or in combination with other errors.
Audit risk (choice C) is the risk of giving an incorrect
audit opinion, while error risk (choice D) is the risk of
errors occuring in the area being audited.
