Final answer:
There are 22 provinces, 5 autonomous regions, 2 special administrative regions, and 4 official municipalities in China; hence the correct answer is D. 31.
Step-by-step explanation:
In China, there are 22 provinces, five autonomous regions, two special administrative regions (SARs) and four official municipalities. The provinces include well-known areas such as Hainan and Taiwan (the latter being self-governing and known as the Republic of China, ROC, but claimed by the People's Republic of China, PRC). the five autonomous regions, which are areas with large non-Han or ethnic minority populations, are Tibet, Guangxi, Xinjiang, Inner Mongolia, and Ningxia. these regions are labeled 'autonomous' by China, indicating they have a degree of self-governance, although in reality this autonomy is quite limited.
The two SARs, Hong Kong and Macau, enjoy a high degree of autonomy compared to other regions in China. Lastly, the four municipalities that have governance on par with the provinces are Beijing, Tianjin, Shanghai, and Chongqing. Thus, the correct answer to the question is D. 31, as this number includes the 22 provinces, 5 autonomous regions, 2 SARs, and 4 official municipalities.
