The correct statement about the election of 1912 is:
The Republican Party did not nominate Roosevelt because he was too progressive.
In the 1912 election, Theodore Roosevelt, a former president, ran as a third-party candidate for the Progressive Party after being unable to secure the Republican nomination, which went to William Howard Taft. The Progressive reform was a significant campaign topic during the election, and Woodrow Wilson was the candidate for the Democratic Party, not the Republican Party.
