c. us president harry truman threatened to use nuclear weapons against china.
d. kim il sung had requested chinas help to declare war against the united states.

Explanation:

During the Korean War, the advance of US-led UN forces toward the Chinese border (Yalu River) posed a direct security threat to China. This prompted Mao Zedong's government to intervene with military tactics against US forces under Douglas MacArthur. The other options are incorrect: Mao did not pre-plan war against the US, Truman did not threaten nuclear weapons against China at this stage, and Kim Il Sung's request was not the core trigger for China's direct military readiness in this context.

Answer:

B. US troops kept marching farther into North Korea, getting closer to the Chinese border.
