What does use of similar shapes in a pattern give?

Unity and order

Unity means that the parts of an artwork seem related, while order means that they appear arranged in a clear and understandable way. In a pattern, repeating similar shapes gives the viewer a sense that the elements belong together. The repeated form creates visual continuity and helps the eye follow the arrangement. Similarity does not require every shape to be exactly identical; related size, outline, or structure can also create unity. This is why repetition is an important tool in design.

Option A is correct because similar shapes make a pattern look connected and organised. Disorderly sound is not a visual effect of shape arrangement, and paper smell is unrelated to composition. Colour temperature describes whether colours feel warm or cool, not whether shapes are alike. Although a pattern may also contribute to balance or rhythm, the most direct effect asked here is unity and order.
