Final answer:
The answer is option C. 'His words were as soft as the petals of a flower' is an example of a simile.
Step-by-step explanation:
The answer is option C. The phrase 'His words were as soft as the petals of a flower' is an example of a simile. A simile is a figure of speech that compares two unlike things using the words 'like' or 'as'. In this example, the words are being compared to the softness of flower petals, indicating that they are gentle and delicate.
Similes are used in writing to create imagery and add depth to descriptions. They make comparisons between two things that are not exactly alike, helping the reader visualize and understand a concept or emotion.
Other options in the question do not contain similes. Option A uses the phrase 'stone heart', which is a metaphor. Option B uses the phrase 'army of children', which is a hyperbole. Option D describes cars waiting impatiently, which uses personification but not a simile.
