Who was thrown in jail after running against Porfirio Diaz in the national election and, while in jail, wrote the Plan de San Luis Potosi?

a. Pancho Villa

b. Emiliano Zapata

c. Pascual Orozco

d. Fransisco Madero

The Plan de San Luis Potosi was written by a group of people, led by Francisco Madero - so we know that the correct answer is d.

Other facts about Madero are also true: he was jailed and he did run in the election of 1910. He was jailed before the election took place actually and the election was rigged: the election fraud was also the topic of the Plan de San Luis Potosi
