Which option shows the most suitable expressive choice of line?

Shaky and broken lines to show fear

Expressive line choice depends on matching the visual character of a mark with the feeling or subject being represented. Shaky, broken, irregular lines can suggest fear, nervousness, insecurity, or instability because they appear uncertain and disturbed. Therefore option A is the most suitable choice. Sharp zigzags generally suggest agitation or energy rather than peace; hard angular lines conflict with the softness of a petal; and completely stable horizontal lines more often suggest rest or stillness than intense conflict. These associations are not absolute rules, since context and surrounding elements matter, but they are useful conventions in school-level visual expression. The answer is unambiguous because only A has a convincing line-emotion match.
