In the middle of the Sprint, the Developers identified a defect. Initially they were not sure about the cause of the defect and hence they involved product owner to discuss it. After the discussion, both the product owner and developers agreed that the defect is indeed a clear gap in feature being developed in their sprint and not a new requirement. The defect should be a)Deferred to the Product backlog since it is the new requirement. b) Deferred since this is not critical defect. c) Fixed in the current sprint.
