The correct answer is C. procedures.
In this scenario, Santeria Trading Inc. has manipulated its accounts to inflate its expenditure, which is a clear violation of internal accounting controls. Procedures are the specific steps and processes that a company establishes to ensure the accuracy and integrity of its financial records.
By manipulating its accounts, Santeria fails to comply with proper accounting procedures, which should include checks and balances to prevent fraudulent activities like tax evasion. Effective procedures would have identified and prevented such manipulation, helping to maintain the company's financial integrity and compliance with tax regulations. Therefore, the correct answer is C. procedures.
