The correct answer is option B) European nations would have gotten more of a foothold in China.
If the imperial dynasty had continued to rule China it is mostly like European nations would have gotten more of a foothold in China.
European nations would have been more vigilant on China if another dynasty would have ruled that nation. Through history, Chinese dynasties have been very powerful and had established domination in different territories of the Asian region. These powerful dynasties were the Han Dynasty(206 B.C.E.-220 E.C.), Tang Dynasty (618-907 C.E.), and Qing Dynasty (1644-1911). That is why European countries would have been more vigilant on China if another dynasty would have ruled that nation.
