What is your question what do you not get?
Hello, I could probably answer it more surely if the question was provided in its original format. But for how it was presented, I believe the answer would be C. A callout.
A callout (or call-out) in publishing is a short excerpt within a bigger text, somehow highlighted to call the reader's attention out to that part, specially. It can be a short string of text with its words connected by lines, dots, arrows, or similar, a sentence in bold separated from the text, or written in a different format, usually in a larger font. - This one is very common in magazines and newspapers. (and I believe this is the type that was presented on this excerpt original format).
The Metamorphosis is a short story written by Franz Kafka. Surrealism is a movement that began in the 1920s. Artists created strange creatures from everyday objects. Surrealism's aim was to allow the unconscious to express itself. The incident inThe Metamorphosis that shows surrealism is Mr. Samsa fatally wounding Gregor with apples (a). Gregor is transformed into an insect right at the beginning of the story. The rest of the story deals with the ways Gregor and his family battle to adjust to his transformation.
