How can variety be added while maintaining shape unity?

By changing size, rotation, or colour within the same shape family

Unity means that the shapes in a composition feel related, while variety prevents the result from becoming dull. Both can be achieved by keeping a common shape family and making controlled changes within it. For example, repeated leaf-like forms may be varied by changing their size, rotation, spacing, or colour. Because the forms still share a visual relationship, the composition remains connected while the differences create interest.

Option A is correct because changing size, rotation, or colour within a related shape family adds variety without destroying unity. Completely unrelated shapes may make the composition feel disconnected, and erasing shapes or changing paper does not create visual variety in the intended way. The changes should be planned rather than random, so the viewer can notice both the common design language and the individual differences.
