Selected Answer: B
B - Rough order of magnitude It is the most correct answer because inviting participants who have previous experience with website redesigns to provide estimates based on their knowledge and experience suggests a high-level, preliminary estimation approach rather than detailed bottom-up or parametric estimation methods. This method helps in providing an initial sense of the effort required for planning purposes.
