A. 1917
B. 1915
C. 1918
D. 1914

Answer 1

A. 1917

Step-by-step explanation:

Germany's submarine attacks on passenger and merchant ships, taking place primarily in the year 1917, was the main motivation behind President Woodrow Wilson's decision to lead the United States into World War I. This action is a far cry from Wilson's previous statement, which was pledging neutrality for the United States. The war finally ended on November 11, 1918.
