Malala Yousafzai's inclusion of words like "suffering," "innocent," "love," and "peace" in her speech is a rhetorical strategy designed to elicit an emotional response from her audience.

These words are not just for decoration or stylistic flair; they serve a purpose in her speech to underscore the urgency and importance of her message.
The other options like metaphor, alliteration, and imagery correspond to different literary devices. A metaphor is a comparison that does not use "like" or "as" (e.g. "Life is a journey"), alliteration is the repetition of consonant sounds at the beginning of words in a sentence or phrase (e.g. "She sells seashells"), and imagery involves using descriptive language to create a picture in the reader's mind.
