The correct answer is A) Taft’s political decisions angered Roosevelt.
Roosevelt ran for the presidency in 1912 because Taft’s political decisions angered Roosevelt.
Once friends or at least colleagues, Taft and Roosevelt had many differences when Howard was the US President. Let's remember that Taft had been the Secretary of War during the Roosevelt administration. So at the end of that Taft's presidency period, Roosevelt had many differences with Taft and formed his own political party: the Progressive party. This decision divided Republicans and of course, this affected the result of the election because the winner was Democrat candidate Woodrow Wilson.
