In Fusion 360, constraints play a critical role in managing geometric relationships and dimensions among sketch entities. When creating a sketch, constraints ensure that shapes are positioned and interact with each other in a controlled manner. For example, when applying a horizontal constraint to a line, it will remain perfectly horizontal regardless of how other features might be modified later. Similarly, applying a dimension constraint allows you to specify exact distances between points or the lengths of lines, ensuring precision in your design.

The effective use of constraints enhances design integrity by allowing you to manipulate a sketch as a cohesive unit. Making changes to one part of the sketch will automatically adjust connected elements according to the established constraints, promoting efficiency and reducing the potential for errors during the design process.

The role of constraints differs significantly from the other listed options. They do not relate to controlling the visual aesthetics, defining colors for shapes, or applying materials to the model. Instead, constraints are fundamentally about maintaining the functional and geometric relationships within the sketch, making option B the most accurate description of their role.
