Somewhat before the time of Mauryan empire, about ______ years ago, emperors in China began building the Great Wall.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 2400.
Around 2400 years ago, somewhat before the Mauryan Empire in India, the initial construction of what would become the Great Wall of China began. During the Qin Dynasty (around 221-206 BCE), Emperor Qin Shi Huang ordered the connection and extension of existing fortifications to protect against invasions from the north. While the most recognizable sections of the Wall were built much later during the Ming Dynasty, the origins of this immense defensive structure do indeed predate the Mauryan period.
