Answer:
A The United States agreed not to seek further territorial expansion in the Pacific.
Step-by-step explanation:
The Treaty of the Four Powers was an agreement signed by the United States, the United Kingdom, France and Japan during the Naval Conference of Washington on December 13, 1921, following the Lansing-Ishii Agreement between the United States and Japan.
Under the pact of the four powers, the parties agreed to maintain the status quo in the Pacific, to respect the respective territorial possessions, not to try to expand territorially and to consult each other in the case of differences over territorial possessions. However, the main result of the treaty was to end the Anglo-Japanese alliance of 1902.
