How much work must the Developers do to a Product Backlog item it selects for...

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.
