The correct answer is "Cut-off oil sales to Japan."

What the United States did that led to Japan's attack on Pearl Harbor was that the US cut-off oil sales to Japan.

At the end of July ad the beginning of August 1941, the United States federal government imposed an embargo on oil and gas exported to Japan. In those years, almost 75 to 80% of oil came from America. So this decision really affected Japan that depended too much on oil.

This was a major cause for the beginning of the war with Japan because, in December 1941, the Japanese Air Force attacked the United States Navy base in Pearl Harbor, Hawaii.

After the attack, US President Franklin D. Roosevelt asked Congress for a declaration of war, and that is how the US entered World War II.
