How can line help tell a story in a picture?

By showing action direction and mood

Direct answer: A is correct. A picture can communicate a story without sentences because visual clues show what is happening and how a person or scene feels. Lines are important clues: slanting or sweeping lines may suggest movement, while calm horizontal lines may suggest stillness. Sharp, broken, or strongly angular lines can make a scene feel tense, and soft curved lines can suggest gentleness or calm. The viewer reads these directions and qualities together with the figures and objects. A is correct because line can communicate both action direction and mood. B is wrong because the price of paper is not normally communicated by a drawn line. C is wrong because changing a frame changes the display, not the story inside the picture. D is wrong because colour cannot be smelled, and smelling it is unrelated to line-based storytelling. Memory cue: expressive lines show what is moving and how it feels.
