Answer:
B. first black man to vote in the United States
Explanation:
Benjamin Banneker was known as one of the early successful African Americans in the United States due to his exposure, level of education, occupation, and most importantly his non slavery background.
It is true that he was a surveyor of the nation's capital, having worked under Major Andrew Ellicott in a survey that ascertained the actual borders of the DC, the federal capital of the United States.
It is also true that he knows mathematics, astronomy, and authors some books in his lifetime.
It is also true that he was a son of a freed slave. His mom was a free African-American woman while his dad was, a former slave.
What is not true, however, is that he was the first black man to vote in the United States as that honor goes to Thomas Mundy Peterson.
