How can an artist add variety to rhythm?

Correct answer: By slightly changing the colour, size, or spacing of repeated elements

In art, variety means introducing controlled differences without destroying unity. An artist can preserve the repeated pattern while gently changing the colour, size, direction, or spacing of selected elements. This creates interest and prevents mechanical monotony, yet the recurrence still allows the eye to sense rhythm. Option A is therefore correct. Removing elements, making objects unrelated, or using one isolated dot would weaken or eliminate the rhythm rather than enrich it.
