Self-organization in Scrum means the Developers have autonomy over how they deliver the Sprint Goal. The Scrum Guidestates: "The Developers... are self-managing, meaning they internally decide who does what, when, and how." Option A aligns with this-choosing how to accomplish work is their domain. Option B is incorrect; the Product Owner orders the Product Backlog. Option C is wrong; the Product Owner invites stakeholders to the Sprint Review. Option D is partially true-Sprint length is set by the Scrum Team collaboratively, not just the Developers, and is typically fixed once established. Option E is false; release decisions are the Product Owner's responsibility. Thus, A is the best answer.
