The correct answer is C. 1997.
Hong Kong was transferred from British to Chinese rule on July 1, 1997, in accordance with the Sino-British Joint Declaration, which was signed on December 19, 1984. The Joint Declaration stipulated that Hong Kong would be governed under a “one country, two systems” principle for 50 years after the handover. This means that Hong Kong would retain its own economic, political, and social systems, separate from those of mainland China.
The handover of Hong Kong was a major event in Chinese history. It marked the end of British colonial rule in Hong Kong and the beginning of a new era of Chinese sovereignty over the territory. The handover was also a significant event in the history of Hong Kong. It marked the end of a period of rapid economic growth and development, and the beginning of a new era of uncertainty and change.
The handover of Hong Kong was a complex and controversial event. There were many different opinions about the future of Hong Kong, and the handover was met with both celebration and protest. However, the handover was ultimately a peaceful and orderly process, and Hong Kong has since become a prosperous and vibrant city.
The options A, B, and D are incorrect because they are not the years in which Hong Kong was transferred to China.
