In this question, you ask “which of the following.” However, there is no list of possible authors. Therefore, we cannot be sure that we are giving you the correct answer.
The most likely answer here is Horatio Alger. Alger was a very popular American author in the mid- to late-1800s. He was best known for his “rags to riches” stories. In his stories, a poor boy typically “made good.” The poor boy’s success came from hard work, but also from strokes of luck. The novels emphasized that people could get ahead in the US through hard work and “pluck.” Alger, then, is the most likely answer to your question.
