The correct answer is B. Tang.
Explanation
The Tang dynasty (618-907) was a Chinese dynasty that was characterized by greatness; however, by the year 683, the dynasty was threatened as Emperor Gaozong (successor of emperor Taizong of Tang dynasty) died and his wife Wu Zetian who was also Taizong concubine seized absolute power through corruption and became the first and only empress in China. As empress, Wu Zeiten was ruthless and aimed at ending the Tang dynasty and imposing a second Zhou dynasty (a previous dynasty in China), but she failed and in 705 was forced to resign from her position and the Tang dynasty led by Emperor Zhongzong was restored. So, the correct answer is B. Tang.
