The correct answer is B. Performing organization or customer . Acceptance of quality standards and product quality requirements belongs to the party that has authority over what the product, service, or result must satisfy. Depending on the project context, this may be the customer, the performing organization, the sponsoring organization, or another authorized acceptance body. The project manager is responsible for planning, managing, and controlling the project so that the agreed quality requirements are met, but the project manager does not unilaterally determine acceptance unless specifically delegated that authority. The work package leader manages assigned work and supports compliance within a defined area, but does not normally own final acceptance of product quality requirements. Quality standards and requirements must be accepted by the appropriate business or customer authority because they define whether the delivered output is fit for purpose, compliant, and acceptable for use. In practical terms, the performing organization or customer confirms whether the quality expectations reflect organizational needs, customer requirements, contractual obligations, and acceptance criteria.
