Final answer:
B.They seized control from the ming by elections.
The Manchu established the Qing Dynasty by taking control from the Ming Dynasty through military action. They were initially allowed to pass through the Great Wall to suppress internal rebellions but went on to take Beijing and asserted their rule over all of China by 1683.
Step-by-step explanation:
The Manchu came to start the Qing Dynasty by seizing control from the Ming Dynasty, not through elections or economic dominance, but by military intervention. The Ming Dynasty had become weak due to high expenditures, internal corruption, and external threats.
The Manchu, hailing from northern China, unified under strong military leadership and adopted Chinese administrative practices, including the employment of Confucian officials. When rebellions threatened Beijing in 1644, the Ming general Wu Sangui allowed the Manchu armies through the Great Wall to defeat the rebels. Subsequently, the Manchu forces took control of Beijing and thus began the Qing rule.
In the subsequent years, the Qing Dynasty consolidated its power, reduced military spending and worked on rebuilding the Chinese economy, while promoting traditional Chinese culture. However, it was only by 1683 that all of China was brought under their control after fierce resistance by the remaining Ming loyalists.
