Exam PRINCE2-Practitioner topic 9 question 8 discussion

I think option B is the correct answer. Refer A.19.2 Outline business case :- Reasons why the project is needed and the business option selected. This will later be developed into a detailed business case during the initiating a project process

B. External consultants were employed to conduct a feasibility study to identify the options, their likely costs and benefits. The outline Business Case is a document that provides a high-level view of the project and outlines the expected costs, benefits, and risks associated with the project 1 . It is an important document that helps to ensure that the project is feasible and that the business case is sound. An appropriate entry for the outline Business Case heading within the Project Brief in PRINCE2 is one that outlines the benefits of what is being recommended and provides options to solve the business problem

According to ChatGTP it is also "B"

I think it is B, see ref. A.19.2. Overall project cost and time are (detailed) BC contents.

Or is it more the statement that "external contractors" were selected as a Business Option?

The Outline Business Case should cover the reasons why the project is needed and the business option selected. So I also think B, as the feasibility study would include this information?

I feel the ans need to be B. ref: A19.2
