B. nationalism.

Explanation:

The nationalism that originated in the times of the French Revolution changed over the years. By the beginning of the 20th century, most European peoples identified with a nation state and were willing to defend or go for interests of a homeland.

The nationalism fueled competition over economic, social aspects, and was best explained by the rivarly between the French and the Germans.

Prussian -French war caused the tensions to increase among the former.

The rivalry was also felt between the English and the Germans over the seas. The increased trade and foreign trade also was a important force that brought tensions in other continents.

The concept of Nationalism emerged to the most, in the military propagandas, and the racial and ethnic policies from the Central `powers.

A fierce state of things promoted a national army in  numbers that were unprecedent to the times- and the war effort ultimately was propeled by nationalistic groups that prevailed among societies.
