Answer:
The correct answer is Metaphor.
Step-by-step explanation:
Metaphor is commonly defined as a figure of speech often used in poetry and literature in order to compare two different things. That is to say, Metaphor equates two things which actually are not the same, reason why it is not meant to be taken literally.
In the particular case of the example provided, the author seems to be comparing the rise of the sun with the way that "the kiddo" behaved himself in order to match the complexity of the occasion.
Bearing in mind the explained above, it could be said that the figurative language used in the quote from the book wonder "I knew you would rise to the occasion, kiddo." is Metaphor.
