Answer:
The best answer is d. because not all countries recognize it as a sovereign nation.
Step-by-step explanation:
Taiwan participates in the Olympic Games under the name "Chinese Taipei" due to political reasons. This is a compromise made by the International Olympic Committee (IOC) to allow Taiwan to participate in the Games while avoiding a dispute with China, which claims Taiwan as a part of its territory.
Since 1971, the People's Republic of China (PRC) has been recognized as the sole legitimate government of China by the United Nations and by most countries around the world. As a result, many countries do not officially recognize Taiwan as a sovereign state and instead recognize the PRC's claim to Taiwan.
To avoid a political conflict, the IOC and Taiwan agreed on the compromise of using the name "Chinese Taipei" for Taiwan's Olympic team. This name does not explicitly refer to Taiwan as a separate country or nation and allows Taiwan to participate in the Games without officially recognizing it as a sovereign state.
In summary, Taiwan participates in the Olympic Games under the name "Chinese Taipei" because not all countries recognize it as a sovereign nation, and using this name allows Taiwan to participate in the Games without causing political disputes with China.
