Which auditing process ensures compliance with regulatory standards?

The correct choice is compliance audit, as this specific auditing process is designed to assess whether an organization is adhering to external regulatory standards, laws, and internal guidelines. A compliance audit involves a systematic review of the company's operational processes and compliance policies to ensure they align with applicable regulations and requirements. This type of audit helps organizations identify any gaps in compliance, mitigate risks associated with non-compliance, and ultimately ensure that they meet legal and regulatory obligations.

In contrast, other types of audits serve different purposes. An internal audit focuses generally on reviewing and improving internal controls and processes without a direct emphasis on regulatory standards. An eligibility audit primarily assesses whether individuals or entities meet specific eligibility criteria for programs or services, rather than compliance with broader regulations. A technical audit evaluates the technical aspects of operations, such as the performance or reliability of systems and processes, again not focusing specifically on regulatory compliance.

By understanding the specific function of a compliance audit, it becomes clear why this choice is the best fit for the question about ensuring adherence to regulatory standards.
