Final answer:
The correct answer is option b. The chief advantage of orthographic representation is its ability to accurately represent an object's shape and size. Orthographic drawings are technical drawings that offer clear, to scale, and undistorted views of all sides of an object, essential for precise manufacturing and construction.
Step-by-step explanation:
The chief advantage of an orthographic representation is B. Accurately represents the object's shape and size. Orthographic drawings are a type of technical drawing that represent different sides of an object through a series of individual views. These views, such as the front, top, and side, are drawn to scale and show the object without any distortion that might occur from perspective. By accurately presenting all dimensions and shapes, orthographic drawings allow for precise measurements and a clear understanding of the object's geometry.
In contrast to three-dimensional views, orthographic drawings do not offer a 3D view of the object (Option A), nor do they typically show the object in its environment (Option C). While they may simplify complex shapes for easier visualization, this is not their primary advantage (Option D). Instead, the main benefit of orthographic representation is its ability to communicate exact measurements and shapes necessary for manufacturing and construction processes.
