The 1912 Presidential Election of the United States was one beset with a major change in the parties involved. Particularly is the case of William Howard Taft and Teddy Roosevelt who had previously been from one party but competed against one another after a split in the party.

With their disparaging difference in their supported policies (for instance, the preservation of certain monopolies which Roosevelt supported but was rejected by Taft who wanted them broken up). This difference led to Theodore Roosevelt's decision to run against Taft for the 1912 presidency.
Thus, the correct answer is option a.
