The correct answer is A.
OBJ-4.2: An objective of the starting up a project process is to ensure time is not wasted on initiating any projects that are based on unsound assumptions regarding the project’s scope,
timescales, acceptance criteria, and constraints. The starting up a project process also ensures that there is a business justification for initiating the project (documented in an outline business case), that all the necessary authorities exist for initiating the project, and that sufficient information is available to define and confirm the scope of the project (in the form of a project brief). The process ensures that the various ways the project can be delivered are evaluated and a project approach selected, that individuals are appointed who will undertake the work required in project initiation and/or will take significant project management roles in the project, and that the work required for project initiation is planned (documented in a stage plan).
