Warren g. harding won the 1920 presidential election by promising:

Explanation:

Harding's 1920 presidential campaign said that America needed "not heroics, but healing ... not revolution, but restoration ... not the dramatic, but the dispassionate."  Those are a few samples among several contrasts like that which he drew.  Another was that we needed "not nostrums, but normalcy."  A "nostrum" is a cure or medicine that someone promises will work but doesn't actually work.  The term is used also for political schemes and promises for bringing about social reform or political progress -- and Harding didn't much believe in such schemes.  

Harding, a Republican, promised to move the country away from liberal policies promoted by the previous administration of President Woodrow Wilson (a Democrat).  According to Eugene Trani, writing for the Miller Center at the University of Virginia:  "On most issues related to the economy and foreign trade, Harding was decidedly conservative—determined, actually, to make the federal government serve U.S. business interests."

letter d is correct.
