Answer:
The line from the novel that is an example of amplification is <em>C: "It was wretched weather; stormy and wet, stormy and wet; mud, mud, mud, deep in all the streets."</em>
Explanation:
Let's remember that <em>amplification</em> in literature is a device that authors use in order to <u>embellish a sentence by adding more information to a fact that could have been missed by the reader otherwise.</u> The objective of this device is <em>to increase the readability and worth of the statement.</em> In this particular case, the speaker says "<em>it was wretched weather</em>", he could have left it there, but instead he added that it was "<em>stormy and wet</em>", not only he adds this, he also repeats to stress the idea of the bad weather: "<em>stormy and wet; mud, mud, mud, deep in all the streets.</em>" He even expresses it in a kind of poetic way, he embellishes the sentence by doing this, and that is exactly the meaning of amplification.
