The Daily Scrum is designed for synchronization and impediment reporting. TheScrum Guidestates: "The purpose of the Daily Scrum is to inspect progress toward the Sprint Goal and adapt the Sprint Backlog as necessary, adjusting the upcoming planned work." Developers raise impediments, which the Scrum Master then addresses.
* A:Sprint Planning sets the Sprint's work, not daily sync.
* B:Correct-daily synchronization and impediment reporting.
* C:Retrospective focuses on improvement, not daily progress.

TheScrum Guidedescribes the Sprint Retrospective as an event where the Scrum Team inspects itself and plans improvements, with the Scrum Master playing a dual role: "The Scrum Master participates as a peer team member in the Sprint Retrospective... and ensures that the event takes place and is positive and productive." Option C captures this-participating as a team member and facilitating when needed. Option A (scribe) is too narrow and not required. Option B (prioritizing) is a team decision, not the Scrum Master's alone. Option D (reporting to management) violates Scrum's team autonomy. Thus, C is correct.

TCO encompasses all costs across a product's lifecycle, not just development. While theScrum Guidedoesn't define TCO, the Product Owner's value focus implies a broad view: "The Product Owner is accountable for maximizing the value of the product." Option B-conception, development, operation, and maintenance- reflects this holistic perspective.
* A:Development cost alone is too narrow.

TheScrum Guidemandates that all work selected for a Sprint must meet the Definition of "Done": "The Increment is the sum of all the Product Backlog items completed during a Sprint and the value of the increments of all previous Sprints." During Sprint Planning, the Developers forecast what they can deliver as a "Done" Increment, committing to that scope. Option A reflects this accountability. Option B suggests incomplete work carries over, which violates the Increment's usability requirement. Option C is too vague and not tied to "Done." Option D imposes a process Scrum doesn't require. Thus, A is correct.

The Product Backlog is under the Product Owner's control and can be updated anytime. TheScrum Guide states: "The Product Owner is accountable for effective Product Backlog management," implying ongoing adjustments as needed.
* A:Limiting updates to Sprint Review contradicts its emergent nature.
* B:Refinement is a key activity, but updates aren't restricted to it.
* C:A "change request" process isn't in Scrum.
