Why can low contrast and soft lines be suitable in a calm composition?

They create calm, gentle, and balanced mood

A calm composition usually tries to give the viewer a peaceful, gentle, and stable feeling. Low contrast means that the differences between light and dark, or between neighbouring colours and lines, are not very harsh. Soft lines also avoid a hard or aggressive appearance. Together, these choices can make the picture feel quiet and balanced instead of noisy or dramatic. The effect still depends on the complete composition, but the stated relationship is appropriate.

Option A follows because gentle line quality and limited contrast support a calm mood. Strong contrast, sharp edges, and very forceful lines are more likely to create excitement, conflict, or tension, although context always matters. Option B says low contrast greatly increases tension, which is generally the opposite of its usual visual effect. Option C is wrong because soft lines do not make every object sharp, and option D does not describe a normal purpose of these elements. Thus A is the best choice.
