Answer:
The correct answer to the question, in fact, to the question: Which territories was Bismarck eager to control because they had rich deposits of iron ore, is, B: Alsace and Lloraine.
Step-by-step explanation:
Alsace-Lloraine was a German imperial territory that was born from the annexation of most of Alsace, and a part of Lloraine, as part of the spoils of war after the German Empire, led by Otto von Bismarck, became the victor in the Franco-Prussian war, in 1871. The reason for the desire that Bismarck showed towards these two regions of France, was their rich deposits of iron ore, necessary for weapon and military armament manufacturing.
