The correct answer is A) obedience.
Emperor Qin Shihuangdi was an autocrat, which is a ruler who demands complete obedience.
An autocrat is a despotic individual that demands absolute obedience to its orders. Autocratic government systems are ruled by authoritarian people that concedes no liberties to its citizens. They live in oppression, under the nonchalance and rigid attitude of the autocrat.
That was the case of Emperor Qin Shihuangdi, the founder of the Qin Dynasty, and the one who united China.
