The correct answer is B, because a product Increment does not have to be released to production at the end of each Sprint. The Scrum Guide states that ''at the end of a Sprint, the new Increment must be 'Done,' which means it must be in useable condition and meet the Scrum Team's definition of 'Done'. An increment is a body of inspectable, done work that supports empiricism at the end of the Sprint. The increment is a step toward a vision or goal.'' Therefore, a product Increment must be potentially releasable, but the decision to release it is up to the Product Owner.
