When Gregor, the protagonist in Franz Kafka’s The Metamorphosis, transforms into a giant insect, his relationship with his family hits a low. However, in chapter 2, his relationship with his sister, Grete, evolves as she becomes his sole caregiver. This means that only his sister can understand what situation Gregor has undergone. The theme of the story is

the closeness between family members. the answer is letter B.

A. The loneliness of human life.

Reasoning: The main character in The Metamorphosis struggles on his own to get out of bed as an insect, which could represent how sometimes individuals feel so miniscule in the world, and refuses anyone to see him in his state. The character's fear of somebody finding out about his condition, especially his family, shows the division between individuals and the rest of society, which is a sort of definition of isolation in itself.
