When should the certification body accept the audit?

Comprehensive and Detailed In-Depth Explanation:

Before accepting an audit, the certification body must assess the integrity of the auditee and the nature of its operations to ensure compliance feasibility.

Clause References:

ISO/IEC 17021-1:2015, Clause 9.1.2 – Audit Planning:

The certification body must review the auditee’s background, reputation, and operational complexity before accepting the audit.

Why is the Correct Answer C?

The auditee’s integrity and reputation impact the credibility of certification.

The nature of operations determines audit complexity and resource allocation.

Why are the Other Options Incorrect?

A (Integrity and reputation only) → Correct but incomplete; nature of operations is equally important.

B (Nature of operations only) → Integrity is also a factor, not just operations.

D (No previous major nonconformities required) → Auditees with past major nonconformities can still be audited if corrective actions are taken.
