Answer:
The correct answer is B. The Metamorphosis.
Step-by-step explanation:
Magical realism, as the name itself suggests, is a type of predominantly realistic writing that contains some supernatural, or magical elements as well. Even though it mostly refers to Latin American literature, there are many examples of magical realism in European literature as well, such as Bulgakov's The Master and Margarita or Kafka's The Metamorphosis.
In The Metamorphosis, the protagonist Gregor suddenly turns into a cockroach, which is obviously magical. The realism is the fact that his transformation is a symbol of his routine, unhappy life.
