The correct answer is C. She wants to preserve her family’s Mexican culture even though she no longer lives in Mexico.
Step-by-step explanation:
A character's point of view which is usually linked to the character's beliefs, customs and ideas can be identified by analyzing the character's actions, reactions, and opinions about certain situations which is part of indirect characterization. In the case, of the text presented the narrator states his Grandmother advice him to become a barber because she believes this job would give him money and was not a hard job; additionally to this, the narrator describes his grandmother asked him to marry a Mexican girl instead of a girl from another country as she believes Mexican girls have different virtues from the ones other girls have.
This shows the grandmother of the narrator is afraid of losing the Mexican heritage and because of this she does not want his grandson to marry a girl from a different country, this idea is also linked to the situation of the family as she has this kind of thoughts probably because they do not longer live in Mexico and that is the main reason why her grandson could marry a girl from other country and she feels the need of advising him. Thus, can be inferred from this, but it is not explicitly stated in the text about the grandmother's point of view is that "She wants to preserve her family’s Mexican culture even though she no longer lives in Mexico".
