26. Define the following terms vital to Scrum - User Story, Epic, and Task.
User Story: In a sprint, a user story is a list of things or the smallest unit of work that the scrum team must finish. User stories are owned by the project's product owner. Each user story might be subdivided into several tasks.Epic: An epic story is one that cannot be completed in a single sprint. A single epic could take months to complete. Because a scrum team can't complete an epic in a single sprint, it's broken down into smaller user stories.
