Answer:
simile
Step-by-step explanation:
The sentence uses simile. Simile uses like or as to compare two things to each other. Imagery is describing something in extraordinary detail to create a picture in the reader's mind. While this does give the reader an idea of how the person's daughter looked, it doesn't exactly create a clear picture of what she looked like. Onomatopoeia is words that are associated with a sound. Ex: sizzle, crack, snap, crunch, etc. This can automatically be ruled out because there is no indication that any words like that were used.
Hope this helps! :)
