The correct answer is D. Warren G. Harding's administration is most associated with the Teapot Dome Scandal. It was the scandal which the most harmed Harding's reputation, and it came to light when he was already dead. He was not aware of its illegal aspects. Warren Gamaliel Harding was the 29th US president serving from March 4 1921 util his death in 1923. Although Harding died as the one of the most popular presidents in history, the subsequent exposure of scandals that took place under him, such as Teapot Dome, eroded his reputation.
