The statement that best represents how Harding and Coolidge's presidential policies compare and contrast with each other is: "Both were pro-business, but only Harding’s presidency is famous for scandals."
While both presidents were Republicans who supported pro-business policies, Harding's administration was marked by significant scandals, such as the Teapot Dome scandal, while Coolidge is often remembered for his more conservative and laissez-faire approach to governance with less scandal.
