When is the Sprint Backlog created?
The best two answers are A and C. These two ways of creating Scrum Teams are consistent with Scrum's values because they respect the self-organization and empowerment of the people who will be working in the teams. They also foster openness and courage by allowing the people to express their preferences and opinions about the new structure.
B, D and E are not consistent with Scrum's values because they impose a top-down approach that does not involve the people who will be affected by the change. They also undermine the commitment and focus of the teams by assigning them to work on something they may not be interested in or passionate about.
