Answer:
O Interview with Hispanic teenage girl.
Step-by-step explanation:
A primary source is a source that is used to support an argument or claim made. And that source is primary because of its source, meaning, it is not rewritten or reproduced, or revised. It contains the first-hand account or an account told by a person who is a witness to that particular event.
A quinceañera is a coming-of-age event popular among the Hispanic community when a girl turns 15 years old. This celebration is a sort of welcome party for a girl from girlhood to womanhood. This practice is done to mark the change in the girl and a welcome into the world of adulthood.
An interview with a Hispanic teenage girl will be the best primary source for a quinceañera because she would have already gone through the event herself and would present the best first-hand account of the celebration.
Thus, the correct answer is the fourth/last option.
