Final answer:
The most accurate statement is that the project remains open until all requirements are met, which includes completion of all closing activities such as documenting lessons learned and distributing the final project report, not just finishing the deliverables.
Step-by-step explanation:
The most accurate statement regarding the closure of a project is option 2) The project is open until all requirements are met. This means that despite the project deliverables being completed and being reassigned to another project, the project you are currently closing is not considered officially closed until the project closure process has been completed. This process includes finalizing all activities across all of the project process groups to formally complete the project, confirming the project's deliverables are acceptable, and ensuring that all documentation is signed off, lessons learned are documented and distributed, and the final project report is handed over.
Project closure is critical as it ensures that the project meets the agreed-upon specifications and that any loose ends are tied up before considering it finalized. Hence, neither the reassignment of the project manager to another project nor the completion of project deliverables can be the basis for considering a project closed.
