Explanation:

Analyze the UN advance toward the Yalu River

Using the Korean War knowledge point, after General MacArthur's successful Inchon landing, UN forces pushed North Korean troops back across the 38th parallel and advanced rapidly toward the Yalu River, which forms the border between North Korea and China.

Evaluate Chinese security concerns

As UN forces neared the Chinese border, leaders in Beijing grew deeply concerned that a hostile, Western-aligned military presence on their doorstep would threaten China's sovereignty and security, leading to a potential invasion or attack on Chinese territory.

Identify the reason for intervention

To prevent a hostile force from securing the border, China launched a massive counter-offensive in October 1950, crossing the Yalu River to push UN and U.S. forces back into South Korea. This directly matches option (c).
