Final answer:
In project management, the pre-initiation task of drafting the project charter formally authorizes a project and gives the project manager the authority to use organizational resources, distinguishing it from other tasks such as creating a work breakdown structure, which is done during the planning phase. The correct answer is option b).
Step-by-step explanation:
The question pertains to project management, specifically the tasks performed during the pre-initiation phase of a project. The correct answer to which activity is a pre-initiation task is b) Drafting the project charter. Before the official start of a project, the project manager or team typically drafts the project charter, which is a document that formally authorizes the existence of a project and provides the project manager with the authority to apply organizational resources to project activities. The business case and the identification of stakeholders may inform the project charter, but they are not themselves pre-initiation tasks; rather, they are part of the initial groundwork that defines the project's purpose and scope.
Drawing up a work breakdown structure is a planning activity that occurs later, once the project initiation phase is complete and detailed planning begins. Hence, it wouldn't be considered a pre-initiation task.
