Which line is suitable to show the sharp and sudden effect of lightning?

Correct answer: Zigzag line

Correct answer: D. Artists use the character of a line to suggest what an event feels like. Lightning appears sudden, sharp and irregular, and a zigzag line changes direction abruptly through pointed angles. This makes it effective for representing the flash and energy of lightning in a drawing. Option D is correct because its broken, pointed direction matches the visual impression of a lightning bolt. Option A, a curved line, usually suggests smoothness, softness or flowing movement, so it does not communicate sharp flashes as strongly. Option B, a soft horizontal line, suggests calmness, rest or a level surface and is almost the opposite of lightning’s sudden energy. Option C, a circular line, suggests roundness, enclosure or continuous turning rather than a jagged flash. The choice is about visual suggestion, not the claim that every lightning drawing must use only one type of line. Memory cue: sudden sharp changes in direction—think zigzag.
