The correct answer is D. You receive friendship when you give friendship
Explanation:
A theme is a general statement that describes a valid truth about one aspect of life such as love, family, loneliness, etc. The passage presented better supports the theme "You receive friendship when you give friendship" because in this story the main character Jake makes a friend just after he is friendly with another person. Also, this statement is a theme because it is general enough to describe an important aspect of friendship that does not only apply to this story but to real life.
