The exact extract asks for the quality guideline of Huawei Digital Power and presents checkbox-style choices, so all valid guideline elements must be selected. The correct answer is A, B, C, D. ''Win with quality and build industry-benchmark quality'' is the strategic quality direction. ''Raise a sense of responsibility'' reflects quality ownership, meaning quality is not only the responsibility of an inspection team but of all roles involved in delivery, service, and operations. ''Do the right thing at the first time'' aligns with defect prevention rather than repeated rework. ''Stick to the zero defect principle'' expresses the quality-management target: prevent defects, reduce variation, and create value for customers and partners. Huawei Digital Power public materials consistently emphasize quality-first, lifecycle quality, safety, reliability, and customer value in PV and ESS solutions. Therefore, all four statements match the quality-guideline logic. Reference: Huawei Digital Power quality and lifecycle-safety materials.
