The correct answer is A.
Through this excerpt from Franz Kafka's "The Metamosphosis" we understand a little more about Gregor's reality.
We can see that he has a table covered with samples of different fabrics because he works as a working salesman.
At the same time, we can infer that he does not have very close relationships since, insted of framing a picture with his family or friends, he chooses to frame a picture he took from a magazine.
