Answer:
B. refusing to supply Japan with oil until it ended its expansionist
policies.
Step-by-step explanation:
The United States embargoed all oil exports to Japan in hopes that Japan would stop expanding. Instead, it heightened tensions between the nations and forced Japan to continue to invade to reacquire the lost resource source. The strained relations would explode in the Attack on Pearl Harbor on December 7, 1941.
