A

During World War II, Germany tried to capture the Russian city of Stalingrad because it had a strategic location along the Volga River (answer B).

Explanation:

The Battle of Stalingrad is the most significant and bloody confrontation of World War II, having lasted for five months and ending in a Soviet victory. The tenacity with which both sides tried to achieve their goals contributed heavily to the intensity and length of the conflict.

The reason why both sides wanted to control Stalingrad was its strategic importance. The city was a large armament producer, and its location along the Volga River would allow the forces that held it to control barge traffic along the stream.

There was another reason, one related to the name of the city. Taking the location named after Stalin, the leader of the USSR, would afford Germany a significant morale advantage. However, this idea was never central to the offensive.
