In mein kampf, hitler said driving force of history was a. militarism b. class conflict c. economic development d. race

The correct option is D race. In his autobiographical book Mein Kampf, translated from the German as My Struggle, published in two volumes in 1925 and 1927 and which became the bible of Nazism in Germany, Adolf Hitler describes his political ideology, the process by which he became anti-Semitic and he summarizes his plans for Germany.  

In such book, he argues that the driving force of history was  a fight between races, fight that would end only when the superior race, the Aryan race, achieved its supremacy over all the other races.
