What component identifies the parameters of a design such as mass and surface area?

The correct choice is B, Properties, because it refers to the attributes and characteristics associated with a design or object within a software environment. In CAD applications, Properties encompass essential information such as mass, surface area, volume, and other critical geometric or material data. Accessing this information allows designers to analyze their designs more effectively and make informed decisions regarding optimizations, materials, and overall design performance.

Projected View is typically used to create 2D representations of 3D objects from various angles and does not inherently provide details regarding design parameters. Scale refers to the ratio of a model's size compared to its real-life counterpart, while Rigid Group deals with the constraints applied to components in assemblies, ensuring they maintain their relative positions. Therefore, these components do not serve the primary function of detailing parameters like mass and surface area.
