01 Which line looks like the ground or horizon?
Answer and explanation
Correct answer: C. Horizontal line
Explanation: The governing concept is orientation: a horizontal line extends from side to side and is parallel to the level surface of the ground. Because the horizon is perceived as a level boundary where land or water seems to meet the sky, artists commonly represent it with a horizontal line. Option C is correct. A curved line bends continuously and may suggest a rounded surface or flowing movement; a zigzag line has sharp changes and often suggests energy or roughness; a spiral turns around a centre and does not represent a level horizon. In an actual landscape, the horizon may be hidden or interrupted, but the basic visual convention remains horizontal. Remembering “horizontal” with “horizon” is a useful beginner association.
