The effect of the figurative language in these lines primarily lies in the use of personification and onomatopoeia, which help create a vivid atmosphere and imagery.
Among the options given, the statement "The onomatopoeia helps the reader imagine the soft sounds of the wind" is the most accurate. The use of sound words like "ring-tinkle-ring" and "flit-flit" creates an auditory image that enhances the movement and ambiance of the scene.
However, it is worth mentioning that there is no direct simile present in lines 1 to 12. Therefore, if the focus is purely on the most effective use of figurative language as highlighted, the onomatopoeia response is the best choice.
