The correct answer is B. "The Gospel of Wealth"
Explanation:
Andrew Carnegie lived from 1835 to 1919 and was mainly known for being both an important industrialist and philanthropist as he was not only responsible for the expansion of industry in the U.S. but also during his life he dedicated his time and money to help society. These two fields that defined Carnegie motivated him to write "The Gospel of Wealth" in which he explained wealthy people or people from high social classes should be philanthropists or use surplus wealth to help society. Thus, the essay Andrew Carnegie wrote was "The Gospel of Wealth".
