According to the PMBOK Guide, 7th edition, one of the key activities in the monitoring and controlling phase of a project is to control quality by verifying that the project deliverables conform to the quality standards and requirements. This involves inspecting and testing the deliverables, reviewing the quality documentation, and requesting corrective actions if needed. The other options are either inefficient, ineffective, or not aligned with the quality management principles. References: PMBOK Guide, 7th edition, page 123-124, section 3.5.2.1.
