Which two of the following options do not participate in a second-party audit against ISO...

A second-party audit is conducted by a party having an interest in the auditee—most commonly a customer auditing a supplier—or by another competent party acting on that interested party ' s behalf. Consequently, an auditor from a customer may perform the audit, and an external consultant may conduct it on the customer ' s behalf. Auditor training or professional credentials do not, by themselves, determine whether an audit is first-, second- or third-party. By contrast, a certification-body auditor performs independent third-party certification activities, while an accreditation-body auditor assesses conformity-assessment or certification bodies rather than functioning as a customer-side second-party auditor. Therefore, D and F are the two roles that do not correspond to participation in a normal second-party ISO management-system audit. ISO 19011 provides the overarching framework for internal and external management-system audits.
