Explanation:

Francisco I. Madero was elected president after Porfirio Diaz, who ruled the country in different periods from 1876 to 1911. Letter A is incorrect since Madero was incarcerated before the elections and after that he escaped to Texas, so it was impossible for him to run in the elections. B is also incorrect because Madero was assassinated by order of Victoriano Huerta. C is also incorrect because the Institutional Revolutionary Party was established many years after the Mexican Revolution. D is correct because Madero was forced to look for other ways of becoming president and the war was the way to do it, forcing Diaz to runaway to Paris.
