Rivaling the pyramids of Egypt or even the ancient cities of the Maya as an achievement, the army of terra-cotta warriors created to protect Qin Shi Huang, China’s first emperor, in his afterlife is more than 2,000 years old and took 700,000 artisans more than 36 years to complete them.

took 700,000 artisans more than 36 years to complete them

took 700,000 artisans more than 36 years to complete it

took 700,000 artisans more than 36 years to complete

700,000 artisans took more than 36 years to complete

to complete them too 700,000 artisans more than 36 years

Here, could anybody tell me why the key is B rather than C?

Usually we say " It took me ten minutes to go to school" and " The task is too difficult to complete". Here, why should we supplement "it" after "complete"?

Thank you for your reply!
