The correct answer is C. Project’s value to the business and resources required . The CSSBB source emphasizes that project selection and chartering should be grounded in the business case , financial justification, and required resources. The business case is defined as a short summary of the strategic reasons for the project , normally involving quality, cost, or delivery with a financial justification , and projects that do not show significant financial impact should be stopped or eliminated. The same CSSBB material also states that resources required for a project must be detailed , including qualified people, equipment, machinery, and other support needs.

This makes “value to the business” and “resources required” the two most appropriate factors for prioritization. A project may be attractive in theory, but if it lacks business value or requires unrealistic resources, it should not rise to the top of the portfolio. By contrast, personal preference of a Master Black Belt or Black Belt is not a valid primary criterion in formal project selection. Project length may matter, but it is secondary compared with strategic value and feasibility. Therefore, the CSSBB-aligned answer is C .
