   3. C.As a fixed sequence with no feedback between processes
   4. D.As connected processes whose interfaces need no management

   Explanation: ISO guidance states: "The process approach includes establishing the organization’s processes to operate as an integrated and complete system." The process approach connects processes as a system so their interactions contribute to the intended results.

   Explanation: ISO 9001 states: "person or organization (3.1) that can affect, be affected by, or perceive itself to be affected by a decision or activity" An entity capable of affecting the activity meets the definition of an interested party.

   4. D.The client's preferred certification outcome

   Explanation: The source states: "result of an audit (3.1), after consideration of the audit objectives and all audit findings (3.11)" The conclusion considers the objectives and all findings, rather than a single observation or preference.
