The correct answer is B) parents.
What the author means by "legitimate bosses" are parents.
We are referring to the story of "Barrio Boy," written by Ernesto Galarza. FOr Galarza, the use of figurative language is appropriate in the story to show the folklore of the Mexican traditions and language. In this case, "legitimate bosses" are his parents, because they have all the formal and legal authority to correct or reprehend him when he disobeys their orders. Another good example of the passage of this question is the words written in Spanish: "Mira qué muchachito tan malcriado," which translates into English as "Look, what a disobedient kid!" The word "muchachito" is a common figurative term in Mexico that refers to children.
