Final answer:
The election of 1912 was won by the Democratic candidate, Woodrow Wilson, after a split within the Republican Party between Theodore Roosevelt and William Howard Taft. Option C.
Step-by-step explanation:
The election of 1912 was a seminal moment in U.S. political history, marking a significant turn towards Progressivism. In this election, the former President Theodore Roosevelt challenged the incumbent President William Howard Taft, resulting in a split within the Republican Party.
The election was ultimately won by the Democratic candidate, Woodrow Wilson, who secured the presidency with 42 percent of the popular vote despite the divided Republican opposition.
Wilson's victory with just a fraction of the popular vote illustrated the deep divisions within the Republican party, a break from the past, and the significant influence of Progressive ideals on the future of American politics.
So Option B is correct answer.
