In the simulation test, there is one question I do not agree with the answer that is shown to be correct. Question -> The Agile Scrum approach cannot be applied to all projects. In which case is Scrum the most desirable? A. When the requirements are known upfront for a fast implementation B. When the competence of the developers is relatively low C. When the organization does not want to do user acceptance tests D. When the product requirements may change in the process I had selected the answer D. But the correct answer given by the system is C and explanation is Changing requirements is all right in the Agile Scrum approach. In a Waterfall approach, the changing demands will lead to a never-ending project. Could anybody let me know what is the correct answer ?
