Which example can be a man-made straight line?
Answer and explanation
Correct answer: Edge of a ruler
The governing concept is the distinction between straight and curved line forms, especially in familiar man-made objects. A ruler is manufactured with a long, even edge, so its edge provides a clear example of a man-made straight line. Therefore option A is correct. The curve of a road bends rather than continuing in one direction, while a flower petal and a cloud outline usually have rounded or irregular curves. Their exact appearances can vary, but none is the best example in this set of a deliberately made straight edge. A ruler is also a drawing tool that helps artists produce accurate straight lines, so the example connects both the visual property and its practical use.
