Answer:
B. The U.S. sold Europe goods needed during the war and took over some markets completely
Explanation:
"The total value of U.S. exports grew from $2.4 billion in 1913 to $6.2 billion in 1917. Most of that went to major Allied powers like Great Britain, France, and Russia, which scrambled to secure American cotton, wheat, brass, rubber, automobiles, machinery, wheat, and thousand of other raw and finished goods." - Heather Michon
