Apparently you didn't want my advice and didn't read the link I posted.

Both of your answers are wrong. You're on your own now.

To verify if your answer is correct, let's go through the options:

A. Japanese attack on Dutch Indonesia: The Japanese attack on Dutch Indonesia, also known as the Dutch East Indies, occurred in early 1942 during World War II. However, the United States did not cut off sales of oil to Japan solely based on this attack.

B. Japanese attack on Pearl Harbor: The Japanese attack on Pearl Harbor on December 7, 1941, was a significant event that led the United States to declare war on Japan. As a result, the United States cut off sales of oil to Japan as part of its response to this attack. This action ultimately played a crucial role in Japan's decision to expand its territories.

C. Japanese occupation of southern Indochina: The Japanese occupation of southern Indochina, which included parts of Vietnam, Laos, and Cambodia, occurred between 1941 and 1945. While this occupation did contribute to escalating tensions between Japan and the United States, it was not the immediate reason for the oil sales cut-off.

D. Japanese occupation of Hong Kong: The Japanese occupation of Hong Kong began on December 25, 1941, after Japan won the Battle of Hong Kong against the British. While this occupation had an impact on the overall context of the war, it was not the direct cause for the United States cutting off oil sales to Japan.

Based on the above analysis, your answer B, the Japanese attack on Pearl Harbor, is correct. The United States cut off sales of oil to Japan in response to the attack on Pearl Harbor.
