What structure did Kafka use in the Metamorphosis?

A. He told the story in order, starting from Gregor's transformation.

Explanation:

The most famous book by the Czech writer Franz Kafka not only tells the story of the man transformed into a monstrous insect. In narrating the trajectory of the traveling salesman Gregor Samsa - who upon waking sees his own body metamorphosed into an animal with "hard back and countless paws" - the writer uses a structure that starts from the transformation of Gregor and manages, through metaphors, to contextualize the human condition and the psychic dramas of society.
