Comprehensive and Detailed 200 to 250 words of Explanation From Exact Extract of project-programme-and-portfolio-management of 5th Edition MSP:

The 'Justification' theme in MSP 5th Edition is central to the programme's lifecycle, ensuring that the investment remains desirable, viable, and achievable. It is not simply about choosing the cheapest option; it is about ensuring that the expenditures made are necessary to secure the projected benefits. This is often referred to as the "Value for Money" assessment.

In this case, the use of a specialized external change office is a strategic decision to mitigate the risk of "value leakage"—where benefits are lost because the organization fails to adopt the new ways of working. Option A is the correct answer because MSP 5th Edition explicitly states that the costs of a programme (including specialized support services) must be weighed against the scale of the transformation and the value of the benefits at risk. If the transformation is "significant," as described, the cost of expert change management is often a necessary investment to ensure the Target Operating Model is successfully reached. Option B is incorrect as it describes "contingency" incorrectly; justification is about the primary investment, not just using leftover savings. Option C is a management choice but does not invalidate the justification principle if external expertise is deemed more effective. The justification theme requires the Senior Responsible Owner (SRO) to continually validate that the costs of these services are outweighed by the improved likelihood of benefit realization.
