The correct answer is B. Jonathan understands that he can live without things, but he cannot live without his family.
Step-by-step explanation:
In the text provided the narrator describes the way in which the character called Jonathan goes back home after the war has finished and he recognizes he feels lucky for having all the members of his family including himself alive and also, he finds his old bicycle has also survived the war. But this object does not compare to his family and because of this the narrator uses expressions such as "a miracle too but naturally not to be compared to the safety of five human heads" and "must be accounted also totally inferior to the five heads in the family" that show the most important is the well being of the family and not the bicycle.
On the other hand, a claim is a statement that expresses a position someone has towards some topic or issue; additionally, this claim needs to be supported by evidence that shows what is being claim is valid and logical, considering this, if the information of the text could be used to support a claim the most suitable claim will be "Jonathan understands that he can live without things, but he cannot live without his family" because this claim is connected to the main idea of the text and therefore the text can be used to support this statement as Jonathan behavior portrays the importance of family over things.
