Answer:
C.Republic of China
Step-by-step explanation:
In 1949–1950, the Communist Party of China (CPC) drove the ROC government out of China and into Taiwan (plus some minor Chinese islands), during the events of the Chinese Civil War. ... The ROC selected Taipei as the provisional capital (of China) and declared "martial law" in 1949.
The Republic of China government received Taiwan in 1945 from Japan, then fled in 1949 to Taiwan with the aim to retake mainland China. Both the ROC and the PRC still officially (constitutionally) claim mainland China and the Taiwan Area as part of their respective territories.
