Explanation:

In the 1912 presidential election, Theodore Roosevelt was initially a Republican. But due to differences with the Republican establishment (especially over William Howard Taft), he split from the Republicans and formed the Progressive Party (also known as the Bull Moose Party) to run as its nominee. The other options are incorrect: he didn't join the Democratic Party, nor did he split from the Democrats (he was a Republican) to form a new Republican party or the Populist Party.

Answer:

A. Roosevelt split from the Republicans and formed the Progressive Party.
