I'll be glad to check your answer.

To determine how the Soviet Union responded to the normalization of relations between China and the United States, we can analyze the given options.

A. Brezhnev invited Nixon to visit Moscow: While this event did occur in 1972, it was a direct response to the US reaching out to China, rather than a response to the normalization of relations between China and the US. Therefore, this option is not the correct answer.

B. Soviet companies set up a thriving trade with China: After the normalization of relations between China and the United States, trade between the Soviet Union and China did increase, with the two countries engaging in various economic agreements. So, this option is a potential response by the Soviet Union.

C. The Soviet Union cut off diplomatic relations with China: This is the correct answer to the question. In response to the US-China rapprochement, the Soviet Union severed its diplomatic relations with China in 1969. The relationship between the two countries had been deteriorating for years, and this move further deepened the divide.

D. The Soviet space program ended its collaboration with U.S. scientists: While the Soviet space program did have a competitive relationship with the US during the Cold War, this particular move is not directly linked to the normalization of relations between China and the US. Thus, this option is not the correct answer.

Therefore, the correct answer is that the Soviet Union cut off diplomatic relations with China in response to the normalization of relations between China and the United States.
