Answer:
The literary device used when Herbert tells Pip, "I am quite free from the flavor of sour grapes" is personification. Option D is the right answer.
Explanation:
Personification is a technique by which human traits and qualities like emotions, sensations, desires, speech and gestures are given in the form a metaphor. In other words, it is the representation of an abstract quality in the human form. The above sentence from Charles Dickens's "Great Expectations," shows the use of the literary device personification. Here, Herbert tells Pip that he is free from the flavour of sour grapes. "The flavour of sour grapes" is the personification used in this sentence. It shows that Herbert is relieved to be free from someone with whom he doesn't have a good relation.
