Question

a organic lines
b geometric lines
c modular lines
d balanced lines

Explanation:

The image shows a pattern composed of straight lines and geometric shapes (diamonds). Organic lines are typically curvy and free - flowing, which is not the case here. Modular lines refer to a system of measurement, not the visual appearance. Balanced lines imply a sense of equilibrium in a more general aesthetic sense, but the key characteristic here is the geometric nature of the lines (straight, forming regular shapes).

Answer:

b. Geometric Lines
