The Scrum Guide mandates 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.
