A user story that is too large to complete in one sprint is considered an epic. Agile teams should split it into smaller, valuable, testable stories. The PMI Agile Practice Guide (Section 5.2: User Stories and Decomposition) and Mike Griffiths’ PMI-ACP Exam Prep Book (Chapter 6: Adaptive Planning) recommend breaking down large stories and renegotiating sprint scope collaboratively with the product owner.
Option C is correct: this aligns with collaborative planning and story decomposition.
Option A is rigid and dismisses collaboration.
Option B promotes unsustainable practices.
Option D violates the principle of fixed-length iterations.
