The correct answer is B. Repetition.
Explanation
Repetition is a literary figure that has the function of emphasizing an expression or idea, showing interest or highlighting the expression, and can be used in any type of text, especially literary ones. The repetition can be of a word or a phrase. Consistent with the above, the statement "…and if being bound in that manner, is not slavery, then is there not such a thing as slavery upon earth." uses repetition because it repeats the word slavery twice. So, the correct answer is B. Repetition.
