Verified Answer :

The Interventionists were people who tried to intervene between the foreign policy between the United States and Britain. They claimed that the United States could avoid war if they sent aid to Britain.

The correct answer is A. sent aid to Britain. 

They believed that an intervention on the side of the United States in the war was not necessary, as long as they sent help in the form of weapons or rations or manufactured products or similar to Britain as it would enable Britain and their soldiers to fight the war instead of American people. Eventually, the United States were forced to join the war as well.
