Which of the following is not true regarding the use and importance of symmetry?
a.
it is achieved when parts of an object are arranged along an imaginary center line.
b.
it gives a work of art aesthetic appeal.
c.
it creates differentiation between each part through the use of dimension and scale.
d.
it provides balance for the over all design of a piece of art.

The answer would be letter C. it creates differentiation between each part through use of dimension and scale. The whole concept of symmetry is about balance. So if we use that in art, then symmetry would mean that the dimensions and scales would be symmetrically aligned, which means that they are same. So with this, we can say that the concept of symmetry doesn't create differentiation between two sides but rather it creates balance.
