The correct answer is C.
OBJ-4.3: Only the project board can authorize project initiation, and its activities are covered in the directing a project process. When a project manager’s request to initiate a project is received from starting up a project, the project board must decide whether to allow the project to proceed to the initiation stage. This may be done at a formal project board meeting or without a formal meeting, as long as all members are in agreement, and the project manager is given documented instruction from the executive to proceed with initiation. The project board may appoint project assurance to undertake some of the reviewing and assessing actions (e.g. inspecting the initiation stage plan to confirm it is viable).
