Final answer:
The new refund policy introduces potential liabilities that may impact TWD's financial statements, which increases the audit risk.
Step-by-step explanation:
The answer to this question is A) Increase, as the new policy introduces potential liabilities that may impact TWD's financial statements.
The introduction of the refund policy creates a potential liability for TWD as it guarantees to refund federal and state funding if any municipality fails the site cleanup inspection in 20X2. This introduces uncertainty and risk to TWD's financial statements, which increases the audit risk.
Therefore, the correct answer is A) Increase, as the new policy introduces potential liabilities that may impact TWD's financial statements.
