Explanation
The Cone of Uncertainty is a project management concept that illustrates how uncertainty decreases over time as more information is gathered about a product or project. At the beginning of a project, estimates can vary widely (the wide part of the cone) because little is known. As the team learns more — through discovery, development, and feedback — the cone narrows, reflecting increasing certainty. Option A describes a Gantt chart. Option C describes a Work Breakdown Structure (WBS). Option D describes a Burndown Chart. The Cone of Uncertainty is relevant to Scrum because it supports iterative development — early Sprints reduce uncertainty progressively.
