Answer 2

The correct answer is D. The German use of unrestricted submarine warfare

Basically, Germans started attacking any ship that was sailing in the sea, regardless of who it belonged to or if it was military or civilian. They declared that they would attack anyone who used the sea so they started attacking American ships too. This resulted in the United States entering the war and fighting Germany on land.
