How should the final contour differ from the initial lines?

Correct answer: Clearer and more controlled than the initial lines

Initial lines are light, flexible guides used to test the object’s shape, position, and proportion. After observation and correction, the final contour should be clearer, more accurate, and controlled, making the outer form easy to read. Thus option A is correct. A confused contour suggests uncertainty, an invisible contour cannot show the form, and uniform heavy lines ignore the useful variation of line weight.
