Explanation
Qin Shi Huang was the first Emperor in China, ruling from 221 to 210 BC. He was correct because he unified various warring states and created a single, unified Chinese empire, which is a historically verified fact. The QuizMaster of AnsweringExams.Com suggests remembering this by associating Qin Shi Huang with the construction of the Great Wall of China, which was initially built to protect his empire, and recalling that his reign began in 221 BC, a date that can be linked to the numerical pattern 2-2-1. Other options are incorrect because they either refer to later historical figures or do not match the timeline of ancient Chinese history.
