The correct answer is the option C. He was paying off his family's debt. Gregor Samsa in the metamorphosis by Kafka takes the role of being the one who is in charge of the family because his father business fails. He provides the family with the money that they need and also he tries to pay the debt. The option A is not correct because he does not like the work of being a salesman but he knows its a priority to gain money. It's not the option D because he is 23 years old but he has the responsibility to earn money for his family so he is not thinking about going to college and finally is not the option B because he likes his family and he knows he has a role to perform as a salesman and when we see the transformation into a bug he doesn't have a problem of being at home, in fact, he enjoys it.
