To determine which option was not used by the artist to effectively create a pattern, it's important to consider the typical elements that contribute to patterns in art.
All four options—line, shape, color, and texture—can be used to create patterns. However, if you need to choose the one that might be least associated with traditional pattern-making, it could be argued that:
D. texture
is often less about creating visual repetitiveness (which is a hallmark of patterns) compared to line, shape, and color, which directly contribute to the visual repetition and rhythm in patterns.
However, it ultimately depends on the context of the artwork being referred to. If you have specific examples or further context, that could help clarify the best answer.
