What can be done with hard lines to reduce tension in a picture?

Correct answer: They can be balanced with soft curves and empty space

Correct answer: D, hard lines can be balanced with soft curves and empty space. A hard line has a firm, sharp, or strongly defined character and can create force or visual tension when repeated too much. To soften the overall effect, the artist can introduce curved, gentler lines and allow unmarked areas to breathe. The contrast gives the eye places to rest and prevents every part of the picture from demanding equal attention. A is wrong because making all lines harder increases tension. B is wrong because erasing the subject removes the image instead of solving the design problem. C is wrong because filling every place with black creates heaviness and confusion. Memory cue: sharp marks need quiet marks and breathing space.
