Answer 1

The statement that BEST explains why the United States entered World War I in 1917 is:

D The U.S. had evidence of a threat to its national security.

This refers to factors such as unrestricted submarine warfare by Germany, which threatened American ships and citizens, as well as the Zimmerman Telegram, in which Germany proposed a military alliance with Mexico against the U.S. These actions contributed to the perception of a direct threat to U.S. national security and ultimately led to the decision to join the war.
