If an atmosphere of fear is to be created which use of lines may be suitable?

Correct answer: Sharp, broken, and irregular lines

Direct answer: A is correct. Line quality can influence the emotional atmosphere of an artwork. Sharp, broken, irregular lines interrupt the eye’s movement and create visual tension, uncertainty, or disturbance; these qualities can support a frightening or threatening mood when they fit the subject. B is less suitable because soft, rounded lines commonly suggest gentleness, comfort, friendliness, or smooth movement. C is less suitable because calm horizontal lines generally communicate rest and stability. D is less suitable because decorative curves often suggest beauty, softness, rhythm, or flowing movement. The effect is not automatic: colour, subject, contrast, scale, and context also matter. A frightening picture could use other devices too, but among these choices, A gives the strongest sense of danger and uneasiness. The word “may” is important: it indicates a suitable possibility, not a universal rule. Memory cue: broken and sharp lines disturb the eye; smooth and horizontal lines usually calm it.
