The correct option is B all-or-nothing attitude in regard to acceptance of the League of Nations.
Woodrow Wilson was inflexible when it came to the debate over the Treaty
of Versailles and the League of Nations. Wilson himself proposed a
League of Nations in his Fourteen Points. He was unwilling to compromise
(A). Although Wilson had encountered difficulty with the Allies when
negotiating the peace at Versailles (C), the debate over ratification
was with Congress, not the Allies. Wilson wanted the United States to
participate in the League of Nations, an international body, not to
isolate itself from the world (D). The League of Nations covenant, which
Wilson supported, pledged each member nation to preserve the
independence and territorial integrity of all the other member nations.
Many isolationist Senators opposed this pledge, outlined in Article X of
the covenant, on the grounds that it would limit the freedom of the
United States in world affairs and affect U.S. military actions (E).
