Answer:
A). Race and geographic location.
Step-by-step explanation:
Perspective or viewpoint always play a vital role in assisting the audience to view and understand the text as intended by the author and elicit intended response.
In the given passage, the 'race and geographic location' is the factor that most likely affected the speaker's perspective as the author employs allusions to his race and his native place. He discusses the issues of 'racial inequality' and the pain of 'not belonging to a specific country or having a real home'(due to his hybrid identity). Thus, option A is the correct answer.
