What becomes easier by understanding a cup as a cylinder form?

Understanding the cup’s volume and round opening

The governing concept is reducing a complex object to a basic three-dimensional form. A cup usually has a rounded wall and a circular opening, so a cylinder provides a practical construction guide. The artist can begin with an ellipse for the rim, draw the two sides with a consistent width, and add a curved lower boundary. Shading along the curved side then communicates the cup’s volume, while the inner ellipse and darker interior suggest thickness and depth. Option A is correct because the cylinder helps organise both the body volume and the opening. Option B concerns smell, not drawing; C incorrectly removes three-dimensional structure; and D is unrelated to visual form. The cylinder is a guide, not a claim that every cup is geometrically perfect.
