Answer:
C. American politics tend to be decentralized, full of checks and balances, while China is completely governed by a single party.
Step-by-step explanation:
The American political system and the Chinese political system are very different.
To start, the U.S. is a federal republic: the government is composed of representatives elected by American citizens. The U.S. political system is also decentralized: the federal power only holds those powers explicitely given in the Constitution, the rest is left to the states.
The Chinese political system is centralized. China is not a democracy, the government is not elected by the people. The Chinese Communist Party is the only ruling political party, meaning that China is a one-party state, a system that is typical of communist countries.
