Which of the following activities are associated with the closing phase of a project? (Choose two.)

Risk mitigation is a planning and execution phase activity focused on reducing the probability or impact of identified risks before they materialize, not a closing activity.

Archiving project documents is a core closing phase activity that ensures all project records, deliverables, contracts, and correspondence are stored in an organized manner for future reference and audits. This activity protects the organization by maintaining a historical record of decisions, scope changes, and approvals made throughout the project.

Tracking expenditures is a monitoring and controlling activity performed continuously during project execution to compare actual costs against the approved budget baseline.

Lessons learned is a formal closing phase deliverable where the team reflects on what went well and what could be improved, creating a reusable knowledge base for future projects. This output is documented and stored as an organizational process asset to inform planning and execution of similar future endeavors.

Quality assurance is conducted during the executing and monitoring/controlling phases to verify that project processes meet defined quality standards, not during the closing phase.
